None of the choices are necessarily true. They probably want you to answer (b), but it is possble to burn both of those fuels without releasing significant nitrogen or sulfur compounds.
Sulfurous smog is acombination of air pollution (containing the ycchhy sulfur) and fog.
i couldn't descide if it is 'a' or 'c'
I think DrWLS is right (he usually is!).
