Solution
The correct option is C Photochemical smog
The photochemical reaction is caused by absorption of energy in the form of light. The word smog is formed of smoke and smog. Photochemical smog is the major contributor to the air pollution and is composed of primary and secondary pollutants. Primary being the nitrogen oxides and volatile organic compounds likeUnsaturated hydrocarbons are those that have double or triple covalent bonds between adjacent carbon atoms. e.g., EthyleneAutomobile exhausts, chimney smog and classical smog contain the primary pollutants like the oxides of nitrogen, sulphur, carbon and dust.Hence, the correct answer is 'Photochemical smog'.
