Show answer & explanation
Correct answer: B
Primary air pollutants are emitted directly, such as Carbon monoxide (A-II). Secondary air pollutants form in the atmosphere, like Peroxyacyl nitrate (PAN) (B-I). Chlorofluorocarbons (CFCs) are ozone-depleting substances (C-IV). Aerosols act as Cloud Condensation Nuclei (D-III).
