The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
Among other functions, epithelial tissues also have a role in the protection of underlying and overlying tissues. Also, various materials are exchanged at the surface of epithelial tissues. These materials depend on the type of epithelial tissue and their location. Hence, both the reason and assertion are correct statements, but the given reason is not the correct explanation for the given assertion.
So, the correct option is B.
