Solution
The correct option is A Maxillary
The trigeminal nerve is the largest of the 12 cranial nerves and is both a motor and sensory nerve. The motor portion of the trigeminal nerve is responsible for jaw movement and chewing, while the sensory portion of the nerve provides the sensation of touch over the face as well as on the surface of the eye. There are three major branches of the trigeminal nerve viz., the ophthalmic branch, the maxillary branch and the mandibular branch, which each traverses the skull in different locations. The maxillary branch innervates the upper jaw.
