Solution

The correct option is C
Assertion is correct and reason is incorrect

The breathing rate of aquatic animals is high because the availability of dissolved oxygen in water is low. Hence, aquatic animals such as fishes inhale and exhale faster to so that more oxygen can be obtained from the water.
