Sentence Correction

181. Because of the enormous research and development expenditures required to survive in the electronics industry, an industry marked by rapid innovation and volatile demand, such firms tend to be very large.

(A) to survive
(B) of firms to survive
(C) for surviving
(D) for survival
(E) for firms' survival


I did get the correct answer at B but was confused between B and E. The OE for not E is as follows.

[spoiler]In choice E, the illogical and awkward use of a prepositional phrase (for firms' survival)
buries the needed initial reference to firms in a possessive modifier[/spoiler]

Someone please explain

"such firms" requires an antecedent.

So A,C, D are out.

"firms' survival" is possessive and "such firms" can't refer back to it. E out

Moreover, because of X -> X should be noun or noun phrase. So, "required" should act as adjective not verb.

Answer: B

I was thinking until now that 'required of' is unidiomatic, but hey, its OG and u can't challenge it!
