Each cerebral hemisphere is divided into frontal and parietal lobes by:

a. the oblique sulcus

b. the longitudinal fissure

c. the central sulcus

d. none of the above

The central sulcus.

Explanation:

Central sulcus are the folds present in the cerebral cortex of the brain. The central sulcus is also known as central fissure and was discovered by Luigi Rolando.

The main function of central sulcus is the division of cerebral hemisphere into the parietal lobes and the frontal lobes. The central sulcus also separates the primary somatosensory cortex from the primary motor cortex.

Thus, the correct answer is option (c).
