The answer is D) a molecule made up of three oxygen atoms.
Ozone is a gas that is composed of three oxygen atoms (O3). It is formed when oxygen (O2) molecules are exposed to ultraviolet radiation or electrical discharges, causing them to undergo a chemical reaction and form ozone. Ozone is colorless and has a distinct smell. It is naturally present in small amounts in the Earth's atmosphere and plays a crucial role in filtering harmful ultraviolet (UV) radiation from the Sun. However, at ground level, ozone can be harmful and can cause damage to human health, plants, and materials.
