Solution

## The correct option is B ${\mathrm{SO}}_{2}$The explanation for the correct answer:(B) - Acid Rain is defined as the precipitation of acid in the form of rain. When atmospheric pollutants like oxides of nitrogen and sulphur react with rainwater and come down with the rain, this results in acid rain. The causes of acid rain are Sulphur and Nitrogen particles which get mixed with the wet components of rain. The two strong acids present in acid rain are nitrogen oxide and sulphur dioxide. These two gases react with water in the atmosphere and oxygen in the air to form sulphuric acid and nitric acid.The explanation for the correct answer:(A) -Inorganic nitrate is an endogenously produced food product that appears to have a critical role in blood pressure and cardiovascular health management, which is not causing acid rain.(C) - It is used as a bleaching agentIt is used as a catalyst in the oxidation reaction of sulphur dioxide to sulphur trioxide.It is used as an essential reagent in sulfonation reactions.(D) - Carbon dioxide is used as a fire extinguisher.It is an important gas in the greenhouse effect.It is used in the preservation of fruits.Therefore, the correct option is B,i.e., acid rain is caused due to ${\mathrm{SO}}_{2}$(Sulphur dioxide) gas.
