Answer 1

The correct option is A acid rain

Acid rain is the emission of oxides of sulphur and nitrogen in the atmosphere. This includes burning of fossil fuels containing sulphur and nitrogenous matter (such as coal and oil in furnaces and power stations, petrol and diesel in automobiles).
Due to increase in acid gases in rain, the pH will change due to acid rain.
