**(c)**

If a sphere of mass M and radius R is dropped in a liquid, its weight acts vertically downwards. While upthrust and viscous force acts vertically upwards. Initially the body will be accelerated down. At a certain instant when viscous force F will balance the net downward force, acceleration will become zero and the body will fall with constant velocity.
