ANSWER------(C) O3
(Ultraviolet radiations forms photochemical splitting of oxygen molecules in the stratosphere. The nascent oxygen combines with molecular oxygen to make ozone. In troposphere nascent oxygen comes from nitrogen dioxide.)
Ultra-violet radiation from sunlight causes the reaction that produces which of the following?
(a) CO
(b)SO2
(c) O3
(d) Fluorides
