Which cranial nerve is NOT listed among the sympathetic cranial nerves described?

Explanation:
Sympathetic fibers to the head reach their targets by hitchhiking along arteries and arteries’ branches that accompany several cranial nerves, providing vasomotor and glandular support in the eye and face. The optic nerve, however, is solely a sensory conduit for vision and carries no autonomic fibers. That’s why it’s not described as a sympathetic cranial nerve. The other nerves listed have autonomic components in their distributions through their vascular or glandular pathways, even though parasympathetic functions are more prominent with them.
