Answer:

A.zero work

Explanation:

Physics describes work in a narrow sense as a theoretical reference. In physics, work is a transfer of energy from one system to another. This is a different, and more precise, concept compared to the older or traditional meaning of “work”, e.g. “activity involving mental or physical effort done in order to achieve a purpose or result”. In the latter sense, work is done in moving a load from A to B.

The process of moving a load with zero net work can be described using physics. We imagine moving a load without friction from A to B, e.g. if A and B are at a common elevation and if the object were tied to a rope suspended from a higher point between A and B, then the object could be released from A and swung freely to a soft landing at B. From A to the lowest point, work is done as some potential energy is converted to kinetic energy as the object gains velocity and then in the second half of the journey the reverse happens, and an equivalent amount of kinetic energy is converted to potential energy as the body comes to rest at point B. Even though work is done in each half of the journey, the net amount of work done is zero, due to energy having been transferred in opposite directions.
