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.
