What is an alloy?

Explanation:
An alloy is a material formed by combining two or more elements, usually to improve properties like strength or hardness. The choice stating metals made up of two or more metals fits this idea, since alloys are created by mixing elements to make a new material with different characteristics than a single metal. Examples like brass (copper with zinc) and steel (iron with carbon) show how adding another element changes the material. The other options describe rust (a corrosion process) or pure metals with no alloy content, which aren’t alloys.
