Dirt roads may evoke the bucolic simplicity of another century, but financially strained townships point out that dirt roads cost twice as much as maintaining paved roads.
(A) dirt roads cost twice as much as maintaining paved roads
(B) dirt roads cost twice as much to maintain as paved roads do
(C) maintaining dirt roads costs twice as much as paved roads do
(D) maintaining dirt roads costs twice as much as it does for paved roads
(E) to maintain dirt roads costs twice as much as for paved roads..

as much as / as little as + uncountable nouns

Cost (uncountable) is compared with Maintain (Uncountable)

A- Maintaining is not agreeing with Cost (to agree it should be costing)---Gerund problem
B- to maintain agrees with the cost- using rule and

DO can be used. Its not mandatory. Do is added here to constrain the COST word-Think of it as a pointer

Any other explanation from the members would be great.

Cheers

Cost could be both "noun" and "verb"

Costs have been cut by 30 to 35 percent - Noun

The cost of sugar has increased three-fold - Noun

However, If something costs a particular amount of money, you can buy, do, or make it for that amount then cost is a verb

The best GMAT book, the OG, doesn't cost much - verb... here cost is used in the "be" form.. option B uses cost in its verb form

Just a tip - Let's underline the suspect portion of the sentence at all times :-)

C is not llel----for it to be correct it should be

maintaining dirt roads costs twice as much as maintaining paved roads do

Choice C incorrectly shifts the meaning by comparing cost of maintaining paved roads with the cost of dirt roads itself.
I am on a break !!

A) dirt roads cost twice as much as maintaining paved roads
wrong comparison: dirt road vs maintaining ...

(B) dirt roads cost twice as much to maintain as paved roads do
Correct dirt road // paved road, and cost // do .

(C) maintaining dirt roads costs twice as much as paved roads do
wrong comparison maintaining vs paved roads:

(D) maintaining dirt roads costs twice as much as it does for paved roads
it has no antecedent

(E) to maintain dirt roads costs twice as much as for paved roads
wrong comparison: to maintain vs paved roads
