its between c and d but comes down to meaning.
Is d grammatically correct? or is the "between" wrong

I don't see any problem with A .Keep it
Quote:
(B) As well as internal networks involving identical operating systems with the same identification protocol

As well as-wrong $$Plus$$parallelism error so eliminate it.
Quote:
(C) Unless internal networks involve identical operating systems, which have the same identification protocol

It changes the meaning.I think the original sentence is not a conditional statement .eliminate it.
Quote:
(D) In addition to an internal network between identical operating systems with the same identification protocol

We don't know whether there are 2 identical systems or many identical systems so cannot use between.eliminate it
Quote:
(E) Together with internal networks between identical operating systems, whose identification protocol is the same

same as D.eliminate it
Please correct me if I am wrong

MANHATTAN REVIEW OFFICIAL EXPLANATION:

The sentence excludes a subset or an event from a larger group. You can eliminate B, D an E because they convey the opposite meaning as they say the subset and the group have the same characteristics. A is wrong because ‘Except for’ should be followed by a phrase, not a sentence. Choice C is the only possible answer.
