A patient is unable to taste in the 2/3 anterior of his tongue. Which cranial nerve is affected?

A. VII: The Facial nerve (VII) is responsible for taste sensation in the anterior two-thirds of the tongue. An inability to taste in this area indicates a dysfunction in this nerve. B. XII: The Hypoglossal nerve (XII) controls tongue movements but does not involve taste sensation. C. V: The Trigeminal nerve (V) provides sensation to the face and mouth but is not responsible for taste. D. II: The Optic nerve (II) is involved in vision, not taste.
