The cerebral cortex is highly folded. Why might this be an advantage for the functions of the cerebrum?

A)The increased surface area increases the area for higher-level thinking.
B)The increased surface area permits greater contact between the cerebrum and the cerebellum.
C)The folds form grooves that let the bones of the skull reach down deeply between brain regions.
D)The folds increase the areas where sensory receptors can reach the brain's surface.
