JEE Main Physics question

Statement 1: Energy released when a mass of one microgram disappears in a process is 9 × 10⁷ J. Statement 2: It follows from E = ½mv².

(A)Assertion is True, Reason is True; Reason is correct explanation for Assertion
(B)Assertion is True, Reason is True; Reason is not correct explanation for Assertion
(C)Assertion is True, Reason is FalseCorrect
(D)Assertion is False, Reason is True

Answer: (C)
