▶ Answer & Explanation
Correct answer: D. Neither 1 nor 2
El Nino is characterized by warmer-than-average sea surface temperatures in the central and eastern tropical Pacific Ocean, while La Nina features cooler-than-average temperatures in the same region. El Nino is known to disrupt global weather patterns, often leading to weaker monsoons in India. While La Nina's effects on the Indian monsoon are less consistent and generally considered less detrimental than El Nino's, it can influence rainfall patterns.
