Inference: Everyone who has graduated from Mon Mar 12, 2012 12:46 pm

This is a question from one of the Manhattan GMAT practise tests

Everyone who has graduated from TopNotch High School has an intelligence quotient (IQ) of over 120. Most students with an IQ of over 120 and all students with an IQ of over 150 who apply to one or more Ivy League universities are accepted by at least one of them.

The statements above, if true, best support which of the following conclusions?
A. Every graduate of TopNotch High School with an IQ of 150 has been accepted by at least one Ivy-League university.
B. If a person is a high-school graduate and has an IQ of less than 100, he or she could not have been a student at TopNotch High School.
C. If a person has an IQ of 130 and is attending an Ivy-League university, it is possible for him or her to have graduated from TopNotch High School.
D. At least one graduate from TopNotch high school who has applied to at least one Ivy-League university has been accepted to one of them.
E. If a high-school graduate has an IQ of 150 and is not attending an Ivy-League university, then he or she did not apply to one of them.

Can anyone explain why D is incorrect?

Stimulus says Most students with an IQ of over 120 and all students with an IQ of over 150 who apply to one or more Ivy League universities are accepted by at least one of them. Consider a student having an IQ of 130 who applies to Ivy-League university. He may NOT be accepted because according to stimulus MOST of the students above 120 and ALL above 150 are accepted. Similarly if all students have IQ (>120 & <150),In this case D is NOT TRUE

Why is A incorrect? Doesn't it agree with what is there in the stimulus?

You missed this from the stimulus: who apply to one or more Ivy League universities
