उत्तर
Oxygen
Category of the remaining terms: Air pollutants
Explanation:
Sulphur dioxide (SO2), Carbon monoxide (CO), and Nitrogen dioxide (NO2) are harmful air pollutants released from vehicles, industries, and the burning of fuels. They cause respiratory problems and contribute to air pollution. Oxygen, however, is not a pollutant; it is a life-supporting gas essential for respiration.
