Solution

The correct option is D Upward
The rain drop is falling with constant speed. Hence, it acceleration is zero. As per Newton's second law of motion, the net force acting on the rain drop is zero. It is balanced by the buoyant force exerted by the water in the upward direction.
The correct option is A.
