Jake Took a Severe Blow to the Head During Last

Jake took a severe blow to the head during last Saturday's hockey game. At the hospital, Jake had a CAT scan and along with finding out that he only suffered a minor
Concussion, Jake's doctor told him he had an unusually large brain for a man his size and age. Jake bragged about this fact at school because he believed this meant he was more
Intelligent than others, until Julie pointed out to him that:

A) scientists believe there is a negative correlation between size and intelligence.
B) although men's brains are larger, their mean IQ scores are lower than women's.
C) women's brains are actually larger than men's brains.
D) the size of the brain is not as important as how efficiently it functions.
