As we move up a body, above the surface of Earth, the change in potential energy will always be:

Explanation

Option C is correct.The change in potential energy is positive when we move a body upward above the surface of the Earth. This is because the potential energy of an object is given by the formula:PE=mgh\text{PE} = mghPE=mghwhere:PE is the potential energy of the object,m is the mass of the object,g is the acceleration due to gravity, andh is the height of the object above the reference point.As we move an object upward, its height h increases. This leads to an increase in potential energy. Therefore, the change in potential energy is positive. Potential energy itself can be zero or even negative depending on the chosen reference level, but in this context, when we raise an object higher, its gravitational potential energy increase
