Answer

Answer:

B. No because some physical changes produce color changes.

Brief Explanation:

Color change can result from physical changes like dissolving a colored substance in a solvent, not just chemical reactions. Chemical reactions involve formation of new substances with different chemical properties, while physical changes don't change the substance's chemical identity.
