B: the work required to lift it to that height is the same.

Explanation:

An object with that given gravitational potential energy will require the same amount of work to lift it to that height.

Gravitational potential energy is the energy possessed by a body at rest in the gravitational field.

The earth is surrounded by a gravitational field.

Work done is often defined as the force applied to move a body through a specified distance. It is related to energy in that is difference between the energy at the final phase and the starting phase. In this problem, the starting energy is 0J At the height where the energy is 62J, work would have been done in the lifting the body through the height. Therefore, the work done in lifting the body is the same as the gravitational potential energy.
