D) oxides of nitrogen
Correct Answer: C
Solution :
In all metropolitan cities of India \[800-1000\] tonnes pollutants are being emitted in air daily. Of which \[50%\] comes from automobile. In Delhi during peak hours automobiles emit \[700kg\] of \[CO,\,\,250kg\] of hydrocarbons and \[60kg\] of\[N{{O}_{x}}\]. On an average, 1000 litres of fuel o a car produces\[350kg\,\,CO\],\[0.6kg\,\,S{{O}_{2}}\], \[0.1\,\,kg\] of lead and \[1.5\,\,kg\] of SPM. In response to harmful effect, carbon monoxide \[(CO)\] combines with haemoglobin of blood and impairs its oxygen carrying capacity. While excess \[C{{O}_{2}}\] attract heating radiations of sun to the earth resulting in risen in temperature of earth (green-house effect) and considered as main green-ousegas.
