b. the hemispheres are exactly equal in function.
c. no functional area of the cortex works alone.
d. the cerebral cortex contains three kinds of functional areas.

The option which does not describe the generalizations in the cerebral cortex is b. The hemispheres are exactly equal in function.

Explanation:

The cerebral cortex is an exclusively grey matter which makes 40% of the mass of the brain. It has areas for motor neurons and sensory neurons to enter into it and it controls actions like thinking, understanding etc.

The cerebral cortex has two hemispheres; the left hemisphere and the right hemisphere. Each side has different functions to perform.

The cerebral cortex is divided into four lobes and each lobe performs different functions.
