Option D

Explanation:

Lateralization of brain function is a tendency to orient brain’s one side to specific neuronal function or cognitive process. The human brain can be divided into two separate cerebral parts of the brain with an elongated slot connected by callosum.

Lateralization of the brain structure is based on basic trends that are reflected in healthy patients. Therefore, each person's brain develops differently, which leads to different lateralization of individuals. For example, each side of the brain seems to represent body’s one side. It is located on the same side of the cerebrum’s body, but is mainly the anterior component of the forebrain.
