Hint: When some toxic compounds present in air come in contact with rain water acidic pollutants are formed. This is called acid rain. Pollutants are the substances that are harmful for the environment. These are the substances that are the main cause of pollution and acid rain.
Complete step by step answer:
Pollution is the presence of contaminants into the natural environment that cause adverse changes in the environment. It can take the form of chemical substance or energy, like, heat, light or noise. The components that cause pollution are called pollutants. These substances can be either foreign substances or energies or naturally occurring contaminants. Acid rain is caused by the oxides of sulphur and nitrogen. Sulphur dioxide present in the atmosphere reacts with oxygen and water to form sulphuric acid which results in acid rain. Reaction associated is written below
$S{O_2} + \dfrac{1}{2}{O_2} + {H_2}O\xrightarrow[{}]{}{H_2}S{O_4}$
This means sulphuric acid is the cause of acid rain.
Nitric acid is a highly corrosive mineral acid. Its chemical formula is $HN{O_3}$. Oxides of nitrogen react with oxygen, water and other substances to form nitric acid when mixed with water results in acid rain.
$3N{O_2} + {H_2}O\xrightarrow[{}]{}2HN{O_3} + NO$
This means nitric acid is also a cause of acid rain.
Chemical formula of hydrochloric acid is $HCl$. Acid rain contains a small amount of hydrochloric acid. This means hydrochloric acid is also the cause of acid rain.
Since all the three options that is sulphuric acid, nitric acid and hydrochloric acid is the cause of acid rain,
So, the correct answer is Option D .
Note:
Sulphur dioxide is not acid rain. It is the reactant that combines with water in the atmosphere to form sulphuric acid that causes acid rain. Sulphur dioxide is that toxic gas which is responsible for the smell of burnt matches.
