According to the Law of Conservation of Matter, the correct statement is:
B. atoms can be rearranged during a chemical reaction but cannot be added or taken away.
This law states that matter cannot be created or destroyed in a closed system, so the total number of atoms remains constant, although they can rearrange to form different molecules.
