Hint:Acid rain in the atmosphere is caused when the precipitation in the atmosphere is less than $5$. The oxides which cause the concentration in the atmosphere to increase are produced by the combustion of industries, smelters, fossil fuels, vehicles etc.
Complete step by step answer:
Acid rain is caused when in precipitation it has elevated levels of hydrogen ions. This can harm plants, animals and other things in the atmosphere. The acid rain is caused when nitrogen dioxide and sulphur dioxide are emitted. These both gases react in the atmosphere with water molecules. The acid rain can be referred to the deposit of mixture from dry and wet acidic components. The liquids in the value of pH is less than 7 are acidic and the value of pH which are greater than 7 are alkaline. The rain which is clean and unpolluted is called as an acidic pH.
Acid rain is the mixture of sulphuric acid and nitric acid. The ratio of two acids varies depending on the quantities of sulphur oxide and nitrogen oxides present in the atmosphere. These oxides are produced from the combustion of fossil fuels, vehicles etc. The $S{O_2}$ and $N{O_2}$ form sulphuric acid and nitric acid when they get dissolved in water where they are present in majority. Then, these acids dissolve in rain and create it as acidic which is termed as acid rain which affects many things in our environment.
So, the correct answer is option A.
Note:Sulphur dioxide is the important gas which is used for the acidification. Emissions of nitrogen oxides which are oxidized to form nitric acid are of increasing importance due to stricter controls on emissions of sulfur compounds.
