Question

which layer of the atmosphere traps the most pollutants? troposphere stratosphere mesosphere

Explanation:

The troposphere is the lowest layer of the atmosphere, where most weather occurs and where human - made pollutants (like smoke, dust, and harmful gases from vehicles, industries) are released. The stratosphere is mainly known for the ozone layer and has less pollutant trapping as air is more stable and less mixing with surface pollutants. The mesosphere is higher up and has very thin air, so it doesn't trap most pollutants. So the troposphere traps the most pollutants.

Answer:

A. troposphere
