Correct: option B
Raising the book against gravity transfers energy into the gravitational PE store of the book–Earth system.
4
Which statement about a closed system is correct?

Conservation of energy: total energy of a closed system is constant; energy is redistributed between stores.
5
A torch is switched on. Which sentence best describes the transfers?
