Resemblance to someone / something is the correct idiomatic usage , none but (C) resolves the issue.

I know that "resemblance to" is not correct phrase. After resemblance, no preposition is added. Pls make sure on the regard.

The human nervous system and a telephone system superficially resemble each other, not only because the former carries information in the form of electrical impulses and because all of its neural pathways converge in the brain and spinal cord, which together form a kind of central exchange.

(A) The human nervous system and a telephone system superficially resemble each other, not only because the former carries

not parallel_______Not only because_____________but because

(B) The human nervous system and a telephone system bear a superficial resemblance because they both carry

Not parallel , And triggers a parallelism

(C) The human nervous system bears a superficial resemblance to a telephone system both because the former carries
Correct
1) Non underline part contains because ll of its so we need singular subject
2) Maintains Parallelism

(D) Superficially, a telephone system resembles the human nervous system both because they carry

1) They should not be used mentioned in C
2) Superficially misplaced

(E) There is a superficial resemblance between a telephone system and the human nervous system, not only because they both carry

Not only because ________________but because (Not ||)

The human nervous system and a telephone system superficially resemble each other, not only because the former carries information in the form of electrical impulses and because all of its neural pathways converge in the brain and spinal cord, which together form a kind of central exchange.

(A) The human nervous system and a telephone system superficially resemble each other, not only because the former carries --- ' Not only because' cannot be idiomatic with 'and because' in the non-underlined portion. 'And' will pair only with 'both' correlatively.


(B) The human nervous system and a telephone system bear a superficial resemblance because they both carry -- This point is a critical factor. The plural 'they' does not gel with the singular its in the non underlined part.

(C) The human nervous system bears a superficial resemblance to a telephone system both because the former carries-- The only correct choice that jumps the pronoun trap.

(D) Superficially, a telephone system resembles the human nervous system both because they carry --- The pronoun trap

(E) There is a superficial resemblance between a telephone system and the human nervous system, not only because they both carry -- suffers from both the correlative conjunction error and the pronoun trap.

However, for a quick fix, the pronoun trap alone can help eliminate three choices in a stroke.
