Solution
The correct option is D Lead
Automobiles burn petroleum inefficiently causing 80% of air pollution and 75% of noise pollution in urban areas. They release hydrocarbons (13.7%), carbon monoxide (77.2%), nitrogen oxides (7.7%), sulphur oxides, ammonia, aldehydes and lead (90% of total lead poisoning). Lead is present in petroleum in the form of Pb(CH3)4 and Pb(C2H5)4 as antiknock agent.So, the correct answer is 'Lead'.
