If both the Assertion and Reason are incorrect.

(D) Lenz's law states that the direction of the induced $emf$ is always such that it opposes the change in magnetic flux that produces it.This law is a direct consequence of the law of conservation of energy.If the induced $emf$ were to assist the change in flux,it would lead to an increase in energy without any external work,which is impossible.Therefore,the Assertion is incorrect,and the Reason is correct.
