The correct response is:
Atoms of one or more substances rearrange into a new substance.
This is a key characteristic of a chemical change, where the identity of the substance changes due to the rearrangement of atoms, resulting in the formation of new substances. In a physical change, the substance may change its appearance or state, but its chemical composition remains the same.
