Option (C) is the right answer.
The ball slows down and comes to rest due to opposing forces of air resistance and frictional force on the ball opposing its motion. Therefore the choice (c) there is a force on the ball opposing the motion is correct. The resistive force is a force, or the vector sum of numerous forces, whose direction is opposite to the motion of a body. Friction is a force that prevents, or tries to prevent, the slipping or sliding of two surfaces in contact.
When the ball rolls on the flat surface of the ground, its motion is opposed by the force of friction (the friction arises between the ground and the ball). This frictional force eventually stops the ball.
