My answer is E,since it clearly compares the vehicles burning methane to the ones buring gasolene and diesel.

You're right, OA is E. Agree with you about paralellism, just can't understand why is used 'less of certain pollutants' and not 'fewer of...'

'==>' : implies
Fewer of certain pollutants ==> if there is a set of certain pollutants (x,y,z,etc.) then few of them are emitted, i.e., not all of the set.
when we use 'less' it ==> amount of the certain pollutants, i.e., all the pollutants in the set of certain pollutants are getting emitted but in the less amount.

I think this is due to the fact that "pollutants" is non-countable noun. One can measure pollutants level, but cannot count pollutants (though its different that one can count "type of pollutants")

Little, much, less are used with non-countable items, like milk, space etc.
Many, few are used with countable items like tables, glasses etc.
Example, there was little crowd, and there were few people

So pollutants here refer to amount,that's why 'less'
Thanks, I got it now

If 'pollutants' were a non-countable noun, everything would be clear at first sight. But I am not sure, maybe you're right However I agree with Sudeep that it refers to amount

In this case less is correct for following reason:
1) meaning implied by original sentence
2) ||ism offered by E.

I think 'fewer' will be correct, in case when original question reflects that and ||ism is offered with vehicles in the answer option. (definitely meaning will be other way around)
