Answer
Exam answer
The AUDITORY NERVE (vestibulocochlear nerve).
Explanation
The auditory nerve carries impulses from the ORGAN OF CORTI in the cochlea to the brain, where they are interpreted as sound.
Its fuller name, VESTIBULOCOCHLEAR, records that it serves both jobs of the inner ear — the COCHLEAR branch for hearing and the VESTIBULAR branch for balance.
Note that this is a SENSORY nerve: it carries impulses TO the brain, which is exactly what the question specifies.
