Quizplus · Accepted Answer

The friction force between two objects acts in the opposite direction to the motion or the tendency of motion of the object. This is due to the fact that the friction force arises due to the interaction between the surface molecules of both objects, which oppose each other's motion. Therefore, option B is the correct choice.
