The correct option is B Both A and B
Smog is formed of smoke and fog and is particularly a pressing problem for large metropolitan cities. The constituents of smog are ground-level ozone, carbon monoxide, nitrogen oxides and volatile organic compounds. The sources of these pollutants are emissions from vehicles, smokestack emission paints etc. Acid rain is formed when sulphur dioxide and nitrogen oxides react with water and oxygen forming more acidic pollutant. Areas having industrial abundance are prone to acid rains. The major sources are coal-fired power plants, burning of fossil fuels etc.Hence, the correct answer is 'Both A and B'
