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 tactile sense organs, unique to aquatic
vertebrates from cyclostome fishes (lampreys and hagfish) to amphibians. It is made up of a series of mechanoreceptors called neuromasts (lateral line organs) derived from ectoderm arranged in an interconnected network along the head and body. The correct explanation for it's presence is to detect movements and pressure changes in the surrounding water.
So, the correct option is 'Both assertion and reason are correct but reason is not the correct explanation of assertion'.
