A batsman hits a cricket ball which then rolls

A batsman hits a cricket ball which then rolls on a level ground. After covering a short distance, the ball comes to rest. The ball slows to a stop because

(a) the batsman did not hit the ball hard enough.
(b) velocity is proportional to the force exerted on the ball.
(c) there is a force on the ball opposing the motion.
(d) there is no unbalanced force on the ball, so the ball would want to come to rest.

Option C is correct.

(there is a force on the ball opposing the motion)

When a ball is rolling on the ground an unbalanced force of friction acts on it which brings the ball to a stop after sometime.
Force of friction opposes the motion.

If there were no unbalanced force of friction and no air resistance a moving object would go on moving forever.
