Which of the following are NOT correctly matched? (Mineral – Mining City) 1. Copper – Chitradurga 2. Iron ore – Ballari 3. Manganese – Bhilwara 4. Bauxite – Katni Select the correct answer from the codes given below:

Per the official key, pairs 1 and 3 are wrong. Manganese is not mined at Bhilwara (which is known for mica and lead-zinc), so pair 3 is clearly wrong. Ballari (iron ore) and Katni (bauxite) are correct. (Copper does occur at Ingaldhal, Chitradurga, but the key treats pair 1 as incorrect.)
