- Oxygen
Correct Option: C
The ozone layer is a layer in Earth’s atmosphere containing relatively high concentrations of ozone (O3). The layer absorbs 97–99% of the Sun’s mediumfrequency ultraviolet light (from about 200 nm to 315 nm wavelength), which potentially damages exposed life forms on Earth.
