JEE Main Physics question

Assertion: Gravitational potential of the earth at every place on it is negative. Reason: Every body on earth is bound by the attraction of earth.

(A)Assertion is True, Reason is True; Reason is correct explanation for AssertionCorrect
(B)Assertion is True, Reason is True; Reason is not correct explanation for Assertion
