Jason is trying to explain to his friend how the body stores energy. Which analogy would best suit Jason's explanation?

The body storing energy is like a toy needing batteries: when the batteries run out, they are thrown away.

The body storing energy is like a car holding gas: the car's gas tank keeps the gas until it is needed.

The body storing energy is like people working to earn money: when they get paid they spend it all.

The body storing energy is like a group of shoppers in a store: individuals may come and go but the numbers stay about the same.
