Solution

The correct option is D Both (i) and (ii) are correct
The frictional force depends on the normal reaction force of the object. That is why it is easier to shift a lighter body on the ground than a heavier body.
Also, frictional force depends on the roughness of the surface in contact. The rougher the surface is, the higher is the frictional force.
The frictional force is independent of the area in contact.
