Here is the image:
Correct answer is B) It is the only cranial nerve that exists from the dorsal aspect of the brainstem. The image shows vertical diplopia, a sign of trochlear nerve disfunction. The only nerve that arrises on the dorsal aspect of the brainstem is again trochlear nerve. So, remember Uma Thurman and the trochlear (IV) nerve.

A) Oculomotor nerve (III)
C) Facial nerve (VII)
D) Vestibulocochlear nerve (VIII)
E) Olfactory nerve (I)
