उत्तर
Its main components are produced by the action of sunlight on emissions of automobiles and factories.
Explanation:
Classical smog is initiated by a mixture of SO2, particulates and high humidity in the atmosphere in cold conditions. A fog of H2SO4 droplets formed condenses on the particulates to form the smog. It is of reducing nature. The gases released by automobiles and factories are not responsible for classical smog.
