A particle moves in the X-Y plane underthe influence of a force such that its linear momentum is $$\overrightarrow{p}(t) = A\left[\hat{i} \cos (kt) - \hat{j} \sin (kt)\right]$$, where A and k are constants. The angle between the force and the momentum is

A

$$0^\circ$$

B

$$30^\circ$$

C

$$45^\circ$$

D

$$90^\circ$$
