The formula for potential energy is
E = mgh
Where m = mass, g = gravitafional acceleration, and h = Height.
So, you can conclude that an increased height contributes to a larger potential energy value.
Potential energy = (mass) x (gravity) x (height)
We have no control over the object's mass, or the acceleration
of gravity. So the only way we can increase the object's potential
energy is to increase its height. (Choice-D)
