Answer:
The correct option is A. Protects aquatic life from changes in air temperature
Step-by-step explanation:
Water has a high heat capacity. This high heat capacity is because of the hydrogen bonds present between the molecules of water. To raise 1 Kelvin temperature of the water, 4.186 Kilo Joules of energy would be required. This feature of water helps aquatic life to survive in high temperatures as well as in low temperatures. When the air is extremely hot, the temperature of the eater will still be less high.
