    Given below are two statements : one is labelled as Assertion A and the other is labelled as Reason R . Assertion A : The kinetic energy needed to project a body of mass mm from earth surface to infinity is 12mgR\frac{1}{2}mgR, where R is the radius of earth. Reason R : The maximum potential energy of a body is zero when it is projected to infinity from earth surface. In the light of the above statements, choose the correct answer from the option given below
