A) Brain size, but not the degree of convolution, is correlated with intelligence scores.
B) The degree of convolution, but not brain size, is correlated with intelligence scores.

Studies have shown that both the size and degree of convolution (or complexity) of the cortex are correlated with intelligence scores. A larger cortex generally indicates more areas for processing and a greater degree of convolution means more surface area for neural connections, both of which have been linked to higher intelligence scores.
