Hi,
[---]
OA : A
Source : GMATPrep Exam Pack 1
This problem was posted here earlier : [---]
I believe it was locked for lack of a legit source for the OA. I can confirm that this is a GMATPrep problem as I encountered this problem on a practice test from the GMATPrep Exam Pack 1.
I am confused between A & B. It would be great to get an explanation from the experts.
Thank you.
