    Water

    Explanation:

    This is actually a chemistry question but I'll answer it anyways

    The definition of a chemical compound is " a chemical substance composed of many identical molecules composed of atoms from more than one element held together by chemical bonds. "

    Compounds are homogenous, which means that they are evenly distributed and have 2 or more different elements from the definition

    Therefore the answer is that water is a compound as its chemical make up is H2O.

    Gold is made up of 1 element

    Oxygen is made up of 1 element,

    Hydrogen is made up of 1 element

    Therefore these options are not viable since they do not contain 2 or more elements.
