Verified by Experts

The correct Answer is:
3
Ozon e,an allotropic form of oxygen,is too reactive to remain for long in the atmosphere at sea level ,but at a height of about `20` kilometers (stratosphere )it is formed from armospheric oxygen by the energy of sunlight.Near earth's surface `O_(3)` is decomposed by dust particles. This Ozone layer protects the earth's surface from an excessive concentration of ultraviolet radiation.
