Solution
The correct option is B Oxides of nitrogen and sulphur
Precipitation of acidic compounds, such as sulphuric or nitric acid onto the ground in wet (rain, fog, snow) or dry (acidic gases and chemicals blown by wind) forms is known as acid rain. It is an impact of excessive addition of pollutants such as oxides of nitrogen and sulphur dioxide (SO2) in the atmosphere. These pollutants are released due to burning of fossil fuels in automobiles, industries, thermal power plants, etc.
When oxides of nitrogen and sulphur dioxide (SO2) react with oxygen, atmospheric water vapour and other chemicals, they form acids such as nitric acid and sulphuric acid. These acids mix with rain water or other substances and reach onto the surface of the earth in wet or dry forms.
