Answer:

c.

Step-by-step explanation:

If the object starts to slide it must be on a slope.

There are 2 forces acting on the object - gravity and the friction between the object and the surface.

If sliding starts then the forces must be unbalanced.

The force of gravity is greater than the friction.
