Solution

The correct option is D I, II and III
The gases released from vehicle exhausts are nitrogen ( $N_{2}$ ), water vapor ( $H_{2} O$ ), and carbon dioxide ( $C O_{2}$ ), carbon monoxide ( $C O$ ), nitrogen oxides ( $N O_{x}$ ), particulate matter (mostly soot) and sulphur dioxide.
Hence option D is correct.
