• B. Nitrogen Dioxide
• C. Methane
• D. Chloroflurocarbons

Answer 1

Answer: (A), (B)

The correct options are
A Sulpher Dioxide
B Nitrogen Dioxide

Combustion of coal releases both $N{O}_2$ and $S{O}_2$ in the atmosphere. Both acts as the air pollutants and have adverse effects on atmosphere. Both of the oxides combines with rain water and form acid rain due to the formation of sulphuric ( $H_{2}S{O}_4$)and nitric acid ($HN{O}_3$).
