- A.1 only
- B.2 only
- C.Both 1 and 2
- D.Neither 1 nor 2
▶ Answer & Explanation
Correct answer: D. Neither 1 nor 2
El Nino is associated with warmer-than-average sea surface temperatures in the central and eastern equatorial Pacific Ocean, while La Nina is characterized by cooler-than-average sea surface temperatures in the same region. El Nino typically leads to a weaker Indian monsoon, while La Nina is often linked to a stronger monsoon. Statement 1 incorrectly places La Nina's cold temperatures in the Indian Ocean and mischaracterizes El Nino's primary location.
