In the sentence above, the pronoun it is incorrect. One stereo system cannot be in two rooms at the same time.
For this reason, eliminate A and B in the SC above. The pronoun it implies that one rail system can be in two places at once.
Is it because "it" refers to exactly same entity and not a similar/generic entity at another place, Please comment if following sentences are correct.
The stereo system in your room is bigger than the stereo system in my room.
The stereo system in your room is bigger than that in my room.
Yes, the issue is that
it refers to the same stereo system, which cannot be in two places at once. Your sentences solve the problem.
In C, the placement of in a European city next to efficient incorrectly implies that the location of the rail system is why the rail system is efficient. Eliminate C.
Can you please explain how you got this meaning.
A modifier should be as close as possible to what it's modifying.
In C,
more efficient in a European city implies that
in a European city is an adverb modifying
efficient and that its purpose is to describe
in what context the rail system will be more efficient.
The intended meaning of the sentence is to describe the
location of the rail system. Thus,
in a European city should be placed next to
rail system:
a rail system in a European city.
Another issue:
The sentence needs to tell us the location of
there directly after the introductory clause:
Because the population there is denser, a commuter rail system in a European city...

Hi Mitch , In E we have
implemented with a comparable population in an American city
.So, there is an " in an American City "
As I noted above, a modifier should be as close as possible to what it's modifying.
In E,
implemented with a comparable population implies that
with a comparable population is an adverb describing how the system will be
implemented.
A population in an American city implies that
in an American city is an adjective describing the location of the
population.
Thus, the comparison in E --
implemented in...implemented with -- is not parallel.
