விளக்கம்

IMD: heat wave if max temperature ≥ 40°C (plains), ≥ 37°C (coast) or ≥ 30°C (hills), with departure criteria.

  • (A) தவறு

    Wrong: the thresholds are swapped.

  • (B) தவறு

    Wrong: plains need 40°C, not 30°C.

  • (C) தவறு

    Wrong: hills need 30°C, not 40°C.

  • (D) சரி

    Correct: IMD thresholds are 40°C for plains and 30°C for hills, so both are wrong.
