Besides PM2.5 and O3, which pollutants are sometimes monitored to meet NAAQS according to the material?

Explanation:
The main idea is understanding which pollutants are commonly tracked under NAAQS beyond PM2.5 and O3. In many air quality networks, the other frequently monitored criteria pollutants are PM10 (coarse particles), NO2 (nitrogen dioxide), SO2 (sulfur dioxide), and CO (carbon monoxide). Monitoring these helps ensure overall compliance with the NAAQS and gives a fuller picture of the pollutant mix in a region. VOCs and methane aren’t part of the NAAQS criteria pollutants, so they aren’t used to satisfy those standards. Lead is a criteria pollutant as well, but the material focus here is on the four listed, which aligns with the given option.
