Well If I am not mistaken, it was kaplan in which i read that out of all choices E is the least frequent as they try to make it appear as that information is not enough.
But i think all these facts and figures will be real close and you cannot make a judgement by them. We should go with intelligent guessing if we have to guess. Some books like Kaplan say a good deal about intelligent guessing. Do read them
Hope that helped
