Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Ozone (O) is an isotope of oxygen which exists in so called ozone layer at a height of about 15-60 km in the middle and upper stratosphere and lower mesosphere. This ozone layer absorbs UV-rays of longer wavelength and protects life on Earth from damaging effects of these radiations. Ozone in the lower atmosphere (troposphere) is regarded as a pollutant.
