I narrowed down the answer choices to D and E. To me it was a toss up and I would have just ended up guessing if this was on the actual exam. Can someone please explain to me why D is incorrect?

Hi Brent, thanks for your explanation. The brackets around the answers was not even something I was looking at when answering the question. Is it typical of GMAT questions to have little tricks like these for their solutions?
