Photochemical smog is primarily caused by the interaction of sunlight with certain chemicals in the atmosphere, leading to the formation of harmful pollutants. Out of the options you provided, fossil fuels (option 1) are the main source of photochemical smog.
To arrive at this answer, you can eliminate options 2 (wind energy) and 4 (nuclear energy) as they are not sources of atmospheric pollution or smog formation. Option 3 (biomass fuels) may emit certain pollutants, but it is not the major contributor to photochemical smog compared to fossil fuels. Therefore, option 1 (fossil fuels) is the correct answer.
Nope.
