- ✓The sun's ultraviolet rays
- DAll of the above
✓
Answer
Correct option: C.
The sun's ultraviolet rays
The ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation $\ce{(UVR)}$ from the sun, protecting life on Earth from its potentially harmful effects. When the sky is clear, there is an inverse relationship between stratospheric ozone and solar $\ce{UVR}$ measured at the Earth’s surface. That is,the lower the ozone levels, the higher the solar $\ce{UVR}.$
