A Correct answer
Explanation

This is the correct answer as all these pollute the air. H2S or hydrogen sulphide is a very poisonous, corrosive, flammable, and explosive gas. Carbon monoxide is a deadly, colourless, odourless and poisonous gas. It is produced by the incomplete burning of various fuels. Cement and asbestos also produce gases that pollute the air.
