D Correct answer
Explanation

The gravitational potential energy of a body of mass m at height h above ground level is given by PE = mgh, where g is acceleration due to gravity. This formula represents the work done against gravity to raise the mass to height h. Option A (mg) is weight, option B (m) is just mass, and option C (g) is just gravitational acceleration - none of these are energy.
