Solution
The correct option is D 70%
Acid rain is caused by a chemical reaction. Basically, rain that has unusually low pH is called acid rain. The most common chemicals that cause acid rain are sulphur oxides and nitric oxides. These substances rise high in the atmosphere where they react with water, oxygen and other chemicals to form more acidic pollutant. Sulphur dioxide on reaction with water and oxygen forms sulphur trioxide which is rapidly converted into sulphuric acid in presence of water. It accounts for 70% volume in acid rain.Hence, the correct answer is '70%'.
