Which of the following is an alloy?

Explanation:
An alloy is a material made by combining two or more elements, usually metals, to give it new properties. Steel is an alloy because it’s formed by adding carbon to iron, creating a mixture that strengthens the metal and improves hardness. Pure copper and pure iron are elements, not mixtures of different elements. Water is a compound made from hydrogen and oxygen, not a metal alloy. So steel is the alloy here because it’s iron plus carbon.
