D Correct answer
Explanation

All of these. In the atmosphere, carbon di-oxide partially reacts with water to form carbonic acid (pumped in the atmosphere  mainly by burning of fossil fuel from volcanoes etc.) In the atmosphere, nitrogen oxide forms a weak solution of nitric acid (pumped in the atmosphere as a secondary pollutant.) In the atmoshere, sulphur di-oxide forms sulphuric acid. This is also called as a secondary pollutant. Answer is Option-5 All of these. Carbon -di -oxide in the atmosphere partially reacts with water to form carbonic acid( pumped in the atmosphere  mainly by burning of fossil fuel, from volcanoes etc. ) Nitrogen oxide in the atmosphere forms a weak solution of nitric acid ( pumped in the atmosphere as a secondary pollutant.) Sulphur -di -oxide in the atmoshere forms sulphuric acid ( this again as a secondary pollutant.)
