An alloy is which of the following?

Explanation:
An alloy is a material created by combining two or more elements, usually metals, to achieve properties that are different or better than a single metal. Melting and mixing the elements before letting them solidify changes characteristics like strength, hardness, or durability. For example, brass is copper plus zinc, bronze is copper plus tin, and steel is iron with carbon and sometimes other elements. This differs from a pure metal, which is just one element, and from ceramics (inorganic compounds) or polymers (long-chain organic molecules). So the best description is a mixture of two or more metals.
