Diesel engines burn as much as 30% less fuel than gasoline engines of comparable size, as well as emitting far less carbon dioxide gas and far fewer of the other gasses that have been implicated in global warming.
A of comparable size, as well as emitting far less carbon dioxide gas and far fewer of the other gasses that have
B of comparable size, as well as emit far less carbon dioxide gas and far fewer of the other gasses having
C of comparable size, and also they emit far fewer carbon dioxide and other gasses that have
D that have a comparable size, and also they emit far fewer of the other gasses having
E that have a comparable size, as well as emitting far fewer of the other gasses having

I was able to reach to the correct answer A through below reasoning, but shouldnt it be burn and emit in option A, let me know your thoughts.

C - far fewer - wrong

gases cant be countable - hence less should be used

the second part in option A - where few is used - it is comparing global warming gases - which can be counted, therefore, few is the correct construction.

Another error in option C is usage of comma + and - signifying independent clause structure, which is not required. We need subordinate clause.

No rest for the Wicked....

Parallel_chase.
here "fewer gasses" implies types of gasses eg. nitrogen, methane
and not the volume/amount of gas themselves.
So "fewer gasses" sounds correct IMO.
