The sentence has several errors of concision. First, the structure “X is of … importance which is why Y is a … prerequisite” is awkward and wordy, and can be more concisely written as follows: “Because [X is … important], [Y is … necessary].” Second, both “some importance” and “necessary prerequisite” are redundant: if something is “important” it has "some importance"; similarly, a “prerequisite” is by definition “necessary.”
(A) This choice is incorrect as it repeats the original sentence.
(B) The singular verb “is” does not agree with the plural subject “records.” In addition, the plural verb "are" does not agree with the singular subject "background check." Finally, the phrase “necessary prerequisite” is redundant.
(C) CORRECT. The redundant and passive clause “X is of significant importance to investment banks” is replaced by the more concise and active clause “they [investment banks] consider X important.” In addition, the redundant and passive clause “a background check is a necessary prerequisite [of investment banks]” is replaced by the more concise and active “investment banks require background checks.” Finally, the entire sentence is rewritten in the concise form “Because X, Y.”
(D) The phrase “some importance” is redundant and wordy. In addition, the meaning of the sentence has been changed to state that “many” of the employees underwent a background check; the original sentence asserted that the background check was required, and, therefore, was submitted to by all.
(E) The structure “the reason X is because Y” is redundant. The proper idiom is either “the reason X is Y” or “Y is because X.” In addition, it is not clear whether the pronouns “they” and “their” refer to “investment banks” or “applicants.”
