Option B

Explanation:

This is a force diagram of a block on an inclined plane.

Gravitational force acts downward and it is the force of attraction between all objects and the earth. It is directly proportional to mass.

Force 1 and 2 are both shear forces that acts parallel to the face of the incline. They are mostly expressed as frictional forces.
