Per the official key, both are true but R is not the correct explanation: big powers have bases in the Indian Ocean for strategic and sea-lane interests of their own. R speaks of benefits to the adjacent countries.

West to east across Central India: Satpura → Mahadeo hills → Maikal range → Chhotanagpur plateau.

Both true and R explains A: the Himalaya has many longitudinal thrust faults (MCT, MBT, HFT) from the ongoing India–Eurasia collision, making it India's most seismically active zone (Zones IV–V).

The Imphal basin was once occupied by a lake (Loktak is its remnant). Its plain formed from lake-bed deposits, so it is a lacustrine plain.

The Damodar flows through a rift (fault) valley between the Chotanagpur plateau blocks, which holds Gondwana coal deposits.

The tropical savanna (e.g. East African grasslands) is called the 'Land of Big Games' because of its large herbivores (zebra, antelope) and predators (lion, cheetah).

Per the official key all three are correct: the Greater Himalaya's crystalline rocks are largely unfossiliferous, the Lesser Himalaya's sedimentary rocks yield marine fossils, and the Siwaliks have remains of early man and Stone Age tools.

Both are true but R does not explain A. Akbar, like Sher Shah, standardised the coinage (A). That the copper dam was the chief copper coin, as in Sher Shah's time, is a separate fact.

Bilgram/Kannauj (1540, Sher Shah defeats Humayun) → Sarnal (1572–73, Akbar's Gujarat campaign) → Dharmat (1658, war of succession) → Jajau (1707, Bahadur Shah I defeats Azam). So II, I, III, IV.

Hatha Yoga was practised by the Nathpanthis (Gorakhnath), and Sufis (e.g. in Amrit Kund translations, Shattari order) also adopted its breathing techniques. Both statements are correct.

Iqta revenue was collected and used by the muqti (iqtadar) to maintain troops; only the surplus (fawazil) went to the Sultan. Revenue was not deposited directly in the Sultan's account.

Gandhi favoured decentralised, village-based development (gram swaraj, cottage industries) and opposed centralised, heavy-industry-led planning.

Both are true but R does not explain A. Article 30 does not define 'minority' (A). That the Constitution recognises only religious and linguistic minorities (Arts 29–30) is a separate fact, not the reason for the lack of a definition.

States have no right to secede, so 1 is correct. Advocating secession is not protected: the 16th Amendment (1963) allows reasonable restrictions on free speech in the interest of sovereignty and integrity. So only 1.

Allocation of Rajya Sabha seats to States/UTs is in the Fourth Schedule, not the Second. Public health and sanitation (State List), Census (Union List) and Anti-defection (Tenth Schedule) are correct.

The Eleventh Schedule (73rd Amendment, 1992) lists 29 subjects for Panchayats. The Twelfth Schedule lists 18 for Municipalities.

The PM's Secretariat (1947) was renamed the Prime Minister's Office in 1977, so 1 is correct. The PMO is headed by the Principal Secretary to the PM, not the Cabinet Secretary (who heads the Cabinet Secretariat). So only 1.

Insects such as the cockroach have colourless (white) haemolymph because it lacks haemoglobin.

Rhizobium bacteria form symbiotic nodules on the roots of leguminous plants (pulses) and fix atmospheric nitrogen.

Charge spreads over the bubble's surface, and the mutual repulsion creates an outward electrostatic pressure, so the radius increases.

Rayon is regenerated (modified) cellulose, not modified starch. Oxytocin is a hormone, aspartame an artificial sweetener and neoprene a synthetic rubber.

Cotton is almost pure cellulose (a carbohydrate). Hair and hooves are keratin, and spider silk is the protein spidroin.

A vacuum flask's double wall with a vacuum stops conduction and convection, and the silvered surfaces cut radiation. So heat is not gained or lost by either (a) or (b).

The pancreas is both exocrine (secretes digestive pancreatic juice into the duodenum) and endocrine (islets of Langerhans secrete insulin and glucagon).

Gypsum is hydrated calcium sulphate (CaSO4·2H2O). China clay is kaolinite (aluminium silicate), corundum is Al2O3 and talc is magnesium silicate.

Silver bromide is used in photography (light-sensitive film), not artificial photosynthesis. Silver iodide is used for cloud seeding, lithium salts for rheumatism/gout, and milk of magnesia as an antacid.

Tulsi's medicinal (antioxidant, antimicrobial) properties come from phenolic compounds such as eugenol and rosmarinic acid, and flavonoids such as orientin and vicenin.

In a typical ecosystem the pyramid of numbers is upright: producers outnumber primary consumers, which outnumber secondary consumers. Primary consumers depend entirely on producers.

Eutrophication is nutrient (N, P) enrichment of a water body causing algal blooms. Their decomposition depletes dissolved oxygen. Both statements are correct.

An environment modified by human activities is called the anthropogenic (man-made) environment.

Species diversity decreases, not increases, from the equator towards the poles (latitudinal diversity gradient). The other statements are true; the Amazon rainforest has the greatest biodiversity.

Lichens are highly sensitive to SO2 and are a well-known bioindicator of air pollution: they disappear from polluted areas.

Pasteurisation is mainly associated with milk (heating to kill pathogens), not tea. Desalination – sea water, reverse osmosis – potable water and denaturation – proteins are correct.

Sodium chlorate (NaClO3) is a non-selective herbicide (weedkiller). Potassium permanganate and bleaching powder are disinfectants/oxidisers.

Flooded paddy fields release methane through anaerobic decomposition, and methane is a potent greenhouse gas.

The International Solar Alliance (launched 2015 by India and France) has its secretariat at Gurugram, Haryana (NISE campus).

Diu became India's first UT to run 100% on solar power during daytime (2017), with about 9 MW of solar capacity.

The global Multidimensional Poverty Index (UNDP–OPHI) has three dimensions: health, education and standard of living (10 indicators).

Wildlife (Protection) Act 1972 → Project Tiger 1973 → Project Elephant 1992 → Biological Diversity Act 2002. So I, III, IV, II.

Western disturbances enter from the west, so winter rainfall in the north-western plains is highest in Punjab and decreases eastwards (West to East).

The Luni rises near Ajmer with fresh water, but becomes saline below Balotra as it crosses salt-bearing soils before ending in the Rann of Kutch.

The Bengal (Ganga) delta is divided into the moribund (dying, north-western, Nadia–Murshidabad), mature and active (south-eastern) deltas.
