Solution

The correct option is C Trigeminal
Sensory neurons carry signals from the outer parts of your body (periphery) into the central nervous system.
Motor neurons (motoneurons) carry signals from the central nervous system to the outer parts (muscles, skin, glands) of your body.
The nerve number V out of the 12 cranial nerves is the trigeminal nerve. The trigeminal nerve has both sensory and motor functions, also known as mixed. It controls somatosensory information (touch, pain) from the face and head; and the muscles for chewing.
Optic, olfactory and auditory are all sensory neurons.
