Solution
The correct option is B
Frictional force
A ball rolling on the ground slows down gradually and finally stops after some time due to Frictional force
This is because when the ball rolls on the ground it comes in contact with the surface of the road and this contact creates a force of friction that resists the movement of the ball and stops the ball for some time.
Earth's magnetic force, electrostatic force, and Gravitational force are noncontact forces.
