The correct answer is B. The opposite direction of the motion.
Friction is a force that opposes the relative motion of two objects or materials. It is caused by the interaction of the microscopic surface features of the two materials. Frictional force always acts in the opposite direction of the motion. For example, when you walk, the frictional force between your shoes and the ground opposes the motion of your feet, which is what allows you to move forward.
Option A is incorrect because frictional force always acts in the opposite direction of the motion. Option C is incorrect because frictional force can only act in two directions: the direction of the motion and the opposite direction of the motion. Option D is incorrect because frictional force does not act in the upward direction.
