A: droplets and crystals scavenge particulates

Explanation:

The air pollution is down after the rainfall as the particles or the pollutant are scavenged or discharged and collects as waste and fall down due to the heavy moisture contents and the raindrops. Hence also involve the flow of the clear and swift air to move them away thus the air pollution gets decreased after the precipitation.
