The facial nerve function includes which of the following?

• A. Facial movement and taste
• B. Hearing and balance
• C. Vision
• D. Smell

Answer: (A)

The facial nerve mainly handles two functions: motor control of the muscles used to express the face, and sensory TASTE from the anterior two-thirds of the tongue (via branches like the chorda tympani). That combination—facial movement plus taste—fits exactly with what this nerve does. The other options point to different nerves: hearing and balance come from the vestibulocochlear nerve, vision from the optic nerve, and smell from the olfactory nerve. So facial movement and taste is the best match for the facial nerve.
