Explanation:

Matter is anything that has mass and takes up space. Light, heat, and sound are forms of energy, not matter. Light from the sun is electromagnetic radiation, heat is a form of energy transfer, and sound is a mechanical wave. None of these have mass in the traditional sense of matter.

None of these
