Answer:

The correct option is: c. Oculomotor

Step-by-step explanation:

Oculomotor nerve is one of the twelve pairs of cranial nerves, emerging from the brain. Oculomotor is the third cranial nerve that originates from the third nerve nucleus in the midbrain.

The oculomotor cranial nerve (CN III), innervates the extrinsic eye muscles including the superior rectus, inferior rectus, and the medial rectus; that are responsible for raising the eyelid and movements of the eye.

The fibers of this nerve innervates the intrinsic eye muscles that are responsible for the constriction of the pupil.
