Which cranial nerve is responsible for facial expressions and taste?

Explanation:
Facial nerve handles both the movements of the face and taste sensation from the tongue. It provides the motor input to the facial muscles that create expressions such as smiling or frowning, and it also carries taste information from the anterior two-thirds of the tongue via the chorda tympani branch. The other options don’t fit because the olfactory nerve is for smell, the optic nerve for vision, and the trigeminal nerve mainly conveys facial sensation and supplies muscles for chewing, not facial expressions or taste.
