Vedclass · Answer

(A) Hydrogen gas $(H_2)$ does not cause atmospheric pollution. When hydrogen is burnt in air,the primary product is water $(H_2O)$,with only trace amounts of nitrogen oxides. In hydrogen fuel cells,the only emission is water vapour. Conversely,$SO_2$ contributes to acid rain and particulate matter. $CO_2$ is a major greenhouse gas. $CO$ is a toxic gas that can lead to the formation of secondary pollutants like tropospheric ozone. Therefore,$H_2$ is the correct answer.
