    2. BOnly 1 and 2
    3. COnly 2 and 3
    4. D1, 2 and 3
    Answer and explanation

    Correct answer: C

    El Nino is a major driver of drought in India, and it's a warm current that appears off the Peruvian coast around December, so statements 2 and 3 are correct. Statement 1 is wrong because India receives deficient rainfall when the eastern Pacific warms during El Nino, not when South Pacific temperatures fall.

    Consider the following statements about El Nino:

    1. AOnly 1 and 2
    2. BOnly 2 and 3
    3. COnly 1 and 3
    4. DOnly 3 and 4
    Answer and explanation

    Correct answer: D

    The question asks which statements are NOT correct. El Nino is a Pacific Ocean phenomenon, so statement 3 (that it starts in the Atlantic) is false, and it affects far more than just the monsoon's regularity, so statement 4 is false too. Statements 1 and 2 are accurate, which leaves 3 and 4 as the incorrect ones.
