Solution

The correct option is B (i) Hygroscopic (ii) Sulphuric acid (iii) Sulphurous aerosol acid (iv) Acid rain
Sulphur dioxide is hygroscopic. When it is in the atmosphere it reacts with humidity and forms sulphuric and sulphurous aerosol acid. These inorganic acids fall as acid rain and disrupt the pH of the soil, in addition to many other adverse effects on the environment.
