Answer 1

The correct option is B 2 and 3 only

Explanation:

El Nino is a climatic phenomenon, which occurs when a vast pool of water in the eastern tropical Pacific Ocean becomes abnormally warm.

Impacts of El-Nino

1. Climatically, the development of an El Niño brings drought to the western Pacific, rains to the equatorial coast of South America, and convective storms and hurricanes to the central Pacific.
2. Severe droughts occur in Australia, Indonesia, and southern Africa.
3. Heavy rains in California, Ecuador
4. El Nino and the Indian monsoon have an inverse relationship. During El-Nino, India receives low rainfall from the monsoon creating drought like conditions.
