Why is identifying the source of atmospheric aerosols useful in policy making?
Answer and explanation
Correct answer: Because natural dust and human pollution can be separated for control measures
Aerosols may come from natural sources such as deserts, sea spray, and volcanoes, or from human activities such as vehicles, industries, and biomass burning. Source identification helps authorities select targeted controls, estimate health and climate effects, and avoid applying the same remedy to every emission. Option A is correct. The other options incorrectly claim that all aerosols come from space, have no significance, or are always beneficial.
