The ability to make things move or change.

Explanation:
Energy is the capacity to do work, to cause motion or change in a system. When you hear “the ability to make things move or change,” that describes energy—the push or power behind actions. For example, a car moves because it has energy turning into kinetic energy, fuels store chemical energy that powers engines, and muscles convert chemical energy into motion. The other words aren’t about that active capacity: a molecule is a basic unit of matter, change is the result or process itself, and stability is a state of balance. So energy best fits the idea of what enables movement or change.
