Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
Lateral line system is a system of sense organs found in aquatic vertebrates such as fishes and aquatic larval amphibians.
Lateral line system is made up of sensory cells of ectodermal origin. However, reason is not correct explanation as it is meant for detecting movement and vibration in the surrounding water and balancing the body while swimming. So, is found in fishes and larval forms of amphibians.
Therefore, the correct answer is option B.
