GMAT Sentence Correction (SC) | Re: In a leveraged buyout, investors borrow huge sums of money

It is a question of parallelism. Hoping to do two things 1. to pay and 2. to profit. Hence "B","C", and "D" are out. Between "A" and "E" the difference is "Company's" and "companies' ." In this case companies are plural . Hence we need a plural apostrophe. Therefore "E" is the answer.
