Solution

The correct option is C $H_{2} S O_{3}$
Sulphur dioxide reacts with water to give sulphurous acid.

$S O_{2} + H_{2} O \to H_{2} S O_{3}$

Oxides of sulphur are pollutants released mainly by oil refineries. These oxides react with rain water, as mentioned above and form acid, thereby contributing to acid rain.
