Answer
C. Elements and compounds are classified as pure substances, and they cannot be separated physically.
Explanation
Elements and compounds are classified as pure substances because they have a fixed composition and distinct properties. They cannot be separated into simpler substances by physical means. Mixtures, on the other hand, can be separated physically and are not pure substances.
