If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.

(A) The Assertion describes Lenz's Law,which states that the direction of induced current is such that it opposes the change in magnetic flux that produced it.Lenz's Law is a direct consequence of the Law of Conservation of Energy. If the induced current were to aid the change in magnetic flux,it would lead to an infinite increase in energy,which violates the principle of conservation of energy.Therefore,the Reason correctly explains the Assertion.
