Is it B? Cause subject verb agreement is correct here, while in other cases it's not ok.

Yes, it's (B). And there is one more split besides Subject-Verb agreement. Idiom: Neither X nor Y.
As for S-V disagreement. Verb that follows Y depends on the singular/plural nature of Y. In (B), it is maintained and thus is correct.

Two rules are tested here:-
1. Idioms should be parallel Neither X nor Y. X and Y should be parallel
2. and the SV pair must agree in number according to the subject of Y.

Choice A
INCORRECT
region’s bears nor the resident pack of gray wolves are not parallel .
Also pack is singular hence the verb suffer should be suffers.

Choice B
Correct.

Choice C
Incorrect
Neither X Nor Y is the Idiom. Neither X or Y is incorrect. Either X or Y is the correct idiom.

Choice D
Incorrect
the is missing before bears and
bears is plural subject and hence verb should be suffer

Choice E
Incorrect
Same error like C

Thanks.
Feedback Appreciated.

Hi team, should the answer A considered incorrect also because we have a parallelism error between noun's noun and noun of noun?

Hello Gio96,

We hope this finds you well.

To answer your query, there is no parallelism break in Option A, as both of these constructions convey the same meaning; "noun's noun" is just less direct than "noun of noun".

We hope this helps.
All the best!

Neither X nor Y verb
verb is singular = Y singular
verb is plural = y plural
resident pack --- is singular so suffers. Hence option B
