Answer: 3. (a), (b), (d) only

Key idea: \(\mathrm{SO_2}\) is converted to \(\mathrm{SO_3}\) and then to sulphuric acid faster when oxidants or surfaces are present.

Particulate matter acts as catalyst and surface, and ozone and hydrogen peroxide are strong oxidants. All three enhance the pollution by sulphur oxides. Hydrocarbons are not involved in this oxidation. Answer: (a), (b), (d), option 3.
