Explanation:

A compound is a substance formed when two or more elements chemically bond together. Compounds can be separated into their constituent elements only by chemical means. Option C states that the substance can be separated into two substances by a chemical process, which is a characteristic of a compound. Option A is true for all matter (elements and compounds).
