Answer: Option (B) is the correct answer.
Step-by-step explanation:
Any activity which requires any physical or mental efforts in order to reach towards the result is known as work.
For example, when Jerome is swinging on a rope then he is doing a physical activity in which he is putting his efforts.
Thus, we can conclude that if Jerome is swinging on a rope and transferring energy from gravitational potential energy to kinetic energy, work is being done.
