All the rain drops hit the surface of the earth with the same constant velocity because when a spherical body of radius r is dropped in a viscous fluid, it is first accelerated and then is acceleration becomes zero and it attains a constant velocity called terminal velocity.

Both A and R are true and R is the correct explanation of A.

Both A and R are true and R is NOT a correct explanation of A.

A is true but R is false.

A is false but R is true.
