标题: 不明白less of...pollutants

164.Because natural gas is composed mostly of methane, a simple hydrocarbon, vehicles powered by natural gas emit less of certain pollutants than the burning of gasoline or diesel fuel.

(A) less of certain pollutants than the burning of gasoline or diesel fuel

(B) fewer of certain pollutants than burning gasoline or diesel fuel do

(D) fewer of certain pollutants than does burning gasoline or diesel fuel

(E) less of certain pollutants than those burning gasoline or diesel fuel

The answer is (E).

为什么是less of certain pollutants：of是什么作用；pullutants是可数名词，为什么可以用less?

Thanks~~~
