Either you transfer the data that was demanded or file a report explaining why you did not submit the overall annual figures
(A) Either you transfer the data that was demanded
(B) You either transfer the data, which was demanded,
(C) You either transfer the data that were demanded
(D) Either you transfer the data, which was demanded
(E) Either you transfer the data, which were demanded
Choice A: This answer choice suffers from a break in parallelism; as the idiom "either...or" is a parallelism marker, the word following both "either" and "or" respectively must be parallel. In the sentence constructed by utilizing this answer choice, "either" is followed by the noun "you" and "or" is followed by the verb "file"; therefore, parallelism is not maintained. Thus, this answer choice is incorrect.
Choice B: This answer choice displays subject-verb disagreement between "data" and "was"; remember, "data" is actually the plural form of the word "datum". Thus, this answer choice is incorrect.
Choice C: This answer choice maintains parallelism and subject-verb agreement. Thus, this answer choice is correct.
Choice D: This answer choice repeats the parallelism error found in Option A. Thus, this answer choice is incorrect.
Choice E: This answer choice repeats the parallelism error found in Options A and D. Thus, this answer choice is incorrect.
Hence, C is the best answer choice.To understand the concept of "Either-Or and Neither-Nor on GMAT", you may want to watch the following video (~1 minute):
