Solution

The correct option is C
negative

Explanation for correct answer:
When a body of mass m is lifted to a height h above the ground, the force acting on a body is in the upward direction against the force of gravity.
Force of gravity is in the downward direction, but the displacement of the body is in the upward direction. So, work done by the force of gravity is negative.
Thus, work done by the force of gravity, when a body is lifted to a height h above the ground is negative. Hence, option C is correct.
