A) Cyclone
B) Tornado
C) La Niña
D) Monsoon
Explanation:
El Niño and La Niña are opposite phases of the El Niño–Southern Oscillation (ENSO), a natural climate pattern in the Pacific Ocean. During El Niño, sea surface temperatures in the central and eastern Pacific Ocean become warmer than normal. In contrast, La Niña occurs when these waters become cooler than average. These climate events affect weather around the world, influencing rainfall, droughts, floods, hurricanes, and temperatures. They can also impact agriculture, fisheries, and water resources in many countries.
