A) Einstein's brain was smaller than average,which has led scientists to believe that the smaller one's brain is,the smarter he is likely to be.
B) brain size is correlated with intelligence only in women.
C) correlations between brain size and intelligence are weak,so brain efficiency is more important to the question of intelligence.

Correlations between brain size and intelligence are weak, so brain efficiency is more important to the question of intelligence. While brain size may have some relationship to intelligence, the correlation is not strong enough to suggest that a larger brain always means higher intelligence. It is more important to consider how efficiently the brain functions rather than its overall size.
