Air quality is related to what?

Answer and explanation

Correct answer: How clean or polluted the air is

Air quality describes the condition of air and the extent to which it is clean or polluted. It is assessed using the presence and concentration of pollutants such as particulate matter, smoke, nitrogen oxides, sulphur compounds, ozone, and other harmful substances. Option B is correct. Oxygen is an important component of air, but its total amount alone does not describe overall air quality; harmful pollutants can affect health even when oxygen remains present. Daily rainfall and atmospheric temperature are weather or climate factors, not the definition of air quality. Good air quality generally means pollutant levels are low enough to reduce risks to people, animals, plants, and the environment.
