The pollution due to oxides of sulphur gets enhanced due to the presence of:

(a) particulate matter
(b) ozone
(c) hydrocarbons
(d) hydrogen peroxide

Choose the most appropriate answer from the options given below:

Sulphur dioxide causes irritation to the eyes, resulting in tears and redness. High concentration of SO₂ leads to stiffness of flower buds which eventually fall off from plants. Uncatalysed oxidation of sulphur dioxide is slow. However, the presence of particulate matter in polluted air catalyses the oxidation of sulphur dioxide to sulphur trioxide.$2{\mathrm{SO}}_2 \left(\mathrm{g}\right) +{\mathrm{O}}_2 \left(\mathrm{g}\right) \to 2{\mathrm{SO}}_3\left(\mathrm{g}\right)$ The reaction can also be promoted by ozone and hydrogen peroxide. ${\mathrm{SO}}_2 \left(\mathrm{g}\right) +{\mathrm{O}}_3 \left(\mathrm{g}\right) \to {\mathrm{SO}}_3\left(\mathrm{g}\right) + {\mathrm{O}}_2 \left(\mathrm{g}\right)$ ${\mathrm{SO}}_2\left(\mathrm{g}\right) + {\mathrm{H}}_2{\mathrm{O}}_2\left(\mathrm{l}\right) \to {\mathrm{H}}_2{\mathrm{SO}}_4\left(\mathrm{aq}\right)$
