Explanation:

The trochlear nerve (cranial nerve IV) is responsible for eye movement (specifically superior oblique muscle control). When a physician tests eye - following movement, they are assessing the function of the trochlear nerve. The vestibulocochlear nerve is for hearing/balance, glossopharyngeal for taste/swallowing, and vagus for visceral functions, so they don't relate to eye - following movement.

Answer:

O trochlear
