    The answer is B. The reason behind this is that El Niño decreases the rate of upwelling of water on the coast. Upwelling occurs when cold, nutrient-rich water "wells up" from the surface. If this process is disrupted manly due to El Niño, the movement of marine life is also affected. As a result, fish either migrate or die due to lesser nutrients coming up in the surface.
