Solution

The correct option is C absorbs ultraviolet radiations which is harmful to human life
The stratospheric ozone layer absorbs ultraviolet light (UV) emitted by the sun. If the solar UV light were able to penetrate the stratosphere and troposphere and reach the earth’s surface, it would seriously damage our ecosystem.
And also it causes skin cancer, blindness, and cataracts.
Hence, the correct option is C.
