"such firms" is the key to find the correct one.
is the answer supposed to be
"for firms to survive"
and not of firms to survive
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 the subject is missing
(B) of firms to survive correct use of the subject Firms.
(C) for surviving the subject is missing
(D) for survival the subject is missing
(E) for firms’ survival the subject is firms, using firms' make this a possessive which does not agree with the modifying phrase
"required of" is the correct idiom.So the ans is B
The subject of the main clause (such firms) presumes a prior reference to the firms in question. Furthermore,
the logical subject of to survive and the logical complement of required should be made explicit. All three
demands are met by B, the best choice. Choices A, C, and D, with no reference to the firms in question, meet
none of these demands. 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.

In my opinion one and all should browse on this.
The explanation is not claiming that required lacks a subject - rather, it claims that required lacks a complement. This is required of someone or something... but the initial option doesn't tell us what or who.
To do this problem, though, I would focus more on the "such firms" clue. "Such" indicates that we've already mentioned the firms once. Choices A, C, and D don't mention the firms, though, so they can't be right. Only B and E mention the firms, and only B clearly tells us both that this is "required of firms" and matches "firms" with "to survive."
A, C, and D can be eliminated because they give a meaning that “enormous research and development expenditures” are required of the ‘industry’. The correct meaning is that such enormous expenditures are required of firms to survive in the electronics industry.
E is wrong because it also fails to convey the meaning effectively.
B is the best choice.
