    1. La Nina is characterised by unusually cold ocean temperature in equatorial Indian Ocean whereas El Nino is characterised by unusually warm ocean temperature in the equatorial Pacific Ocean.
    2. El Nino has adverse effect on South-West monsoon of India, but La Nina has no effect on monsoon climate.

    A)  Only 1

    B)  Only 2

    C)  Both 1 and 2                

    D)  Neither 1 nor 2

    Correct Answer: A

    Solution :

    Exp. [a] La Nina technically operates over Pacific Ocean but since it is found hovering over Port Darwin and South-East Asian region which is adjacent to Indian Ocean, it remains to be seen how the UPSC considers this point. The second statement is false as La Nina is favourable to monsoon.
