Answer

Brief Explanations:

Friction is a force that resists relative motion between surfaces in contact. Its direction is always opposite to the direction of the relative motion or the tendency of relative motion. For example, when you push a box forward, the friction force acts backward to oppose this forward - motion.

Answer:

B. It always opposes the direction of motion.
