Detailed Solution

Gravitational potential energy is the energy stored in an object due to its position in the presence of a gravitational field.
It is given as PE =mgh
Where m = is the mass of the body, g = is the acceleration due to gravity and h = is the height of the body.
We can see that when the mass of the body is constant, the gravitational potential energy depends on the height of the body above the ground. More the height, the more the gravitational potential energy.
Therefore, when an object is dropped from height h, its gravitational potential energy is maximum at height h and then keeps on decreasing as it falls down.

Therefore, 'h' is the correct response.
