What is the basis for calling stratospheric ozone life-protecting?
Answer and explanation
Correct answer: It absorbs ultraviolet rays
The governing concept is the protective function of the stratospheric ozone layer. Ozone absorbs a large fraction of biologically harmful ultraviolet radiation, especially UV-B and nearly all UV-C, before it reaches Earth’s surface. This reduces risks such as skin damage and harm to living cells. Therefore option A is correct. Ozone does not form all clouds, convert nitrogen into food, or transform dust into oxygen.
