Answer 1

The solid component causing air pollution is CO₂.

Explaination:

Carbon (C), typically emitted in the form of soot or fine particulate matter from incomplete combustion, acts as a solid air pollutant. In contrast, carbon monoxide ($\text{CO}$), carbon dioxide ($\text{CO}_2$), and hydrogen sulfide ($\text{H}_2\text{S}$) are all released as gaseous pollutants.
