Answer & Solution

Answer: (Detailed Solution Below)

Option A: Only 1

Detailed Solution:

The correct answer is “Only 1”.
El Niño is characterized by the appearance of a warm ocean current along the coast of Peru in the eastern Pacific, leading to significant climatic changes.

While the warm current can affect marine life, it does not typically increase the temperature of water by 10°C. In fact, the increase in temperature can disrupt normal upwelling processes, which generally decreases the amount of plankton and thus affects the food chain negatively.
