The Areas That Comprise the Association Cortex Are Sometimes Referred

The areas that comprise the association cortex are sometimes referred to as the "silent areas" because:

A) when they are damaged, people lose their hearing.
B) they are responsible for attending to subtle sounds and noises.
C) they are related to vision and physical sensations, which are separate from hearing.
D) when they are stimulated electrically, they neither trigger sensory experiences nor motor responses.
