Friction is a force that ALWAYS acts: b) Opposite the direction of motion.

Here's why:

Friction is a force that resists the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. When an object is moving or attempting to move across a surface, friction acts in the opposite direction of the motion. This is because friction tries to prevent or slow down the movement.

For example, if you slide a book across a table, the book will eventually stop because of the friction between the book and the table. The frictional force is acting opposite to the direction the book was moving.

So, while the materials in contact and the surfaces in contact can affect the magnitude of the frictional force, the direction of the frictional force is always opposite the direction of motion.
