**Statement I:** Linear momentum of a body changes even when it is moving uniformly in a circle. **Statement II:** Force required to move a body uniformly along a straight line is zero.

(A)Statement I is true, Statement II is true; Statement II is a correct explanation for Statement I
(B)Statement I is true, Statement II is true; Statement II is not a correct explanation for Statement ICorrect
(C)Statement I is true, Statement II is false
(D)Statement I is false, Statement II is true
