(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.
When the ball rolls on the flat surface of the ground, its motion is opposed by the force of friction. This frictional force will eventually cause ball to stop. Therefore, the correct answer is (c).
