Assertion: A planet moves faster when it is closer to the sun in its orbit, and vice versa. Reason: Orbital velocity in the orbit of a planet is constant.

(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
