Which of the following is the best example of a compound?

Oxygen
Water
Gold
Carbon

The correct answer is: Water

Water serves as the best example of a compound because it is made up of two different elements—hydrogen and oxygen—chemically combined in a fixed ratio to form a new substance. In contrast, oxygen is a diatomic molecule comprising two oxygen atoms, thus not a compound in the traditional sense. Similarly, gold is a pure element consisting solely of gold atoms, and carbon is also an elemental form, made up entirely of carbon atoms. Compounds, by definition, must consist of two or more different elements that are chemically bonded, which is why water is the correct choice in this scenario.
