Auditory nerve is eighth cranial nerve. It is called as vestibulocochlear nerve. It is the nerve to meant for hearing and balancing your body. The optic nerve is second cranial nerve. It carries sensory signals from your eye to the brain. It arises from the retina of the eye.
I and II
The question is asking what three cranial nerves are purely sensory in their function. Some relevant terms here are olfactory, optic, and auditory or vestibucochlear or acoustic nerves. The only three cranial nerves that are pure sensory in function are cranial nerve #1 : the olfactory nerve (smell), cranial nerve #2 : the optic nerve (sight), and cranial nerve #8 : the auditory/vestibucochlear/acoustic nerve (hearing).
Relay and processing centers for sensory information.
The twelve cranial nerves can be can one of the following types:* Sensory = carry sensory innervation/information to and from certain organs * Motor = carry motor (movement) innervation to certain organs * Mixed/Both = carries both sensory and motor innervation

The thalamus
Neurons that convey sensory information are called 'sensory neurons' or "afferent neurones"
A sensory neuron ALWAYS carries information into the CNS. A MOTOR neuron ALWAYS carries information from the CNS to MUSCLES and other effectors. Sensory in, motor out.

Sensory Neurones
Afferent neurons carry information to the CNS, and efferent neuron carries it away.
