Which region is part of the prefrontal cortex?

The front-most part of the frontal lobe of the cerebral cortex is known as the prefrontal cortex. This part is essentially important in defining the executive properties of the brain. Certain functions such as planning, dealing with a problem, and making decisions are regulated by this part of the brain.

The given problem asks about the region which is the part of the prefrontal cortex.

Option a is the posterior cingulate cortex which is part of the posterior cortex or caudal cortex hence it is incorrect. Similarly, option c is an anterior insulator that is present deep inside the cerebral cortex, covered by frontal, lateral, and operculum. Hence, it is an incorrect answer. Option d is the putamen that is present in the telencephalon and not the prefrontal cortex hence it is also not the correct answer. Option e is ventral striatum is also located deep inside the brain and is an incorrect answer.
