Select and explain. 
A. Facial nerve, B. Glossopharyngeal nerve, C. Lingual nerve, D. Vagus nerve
A: Facial nerve
Answer: A: Facial nerve 
Explanation: The chorda tympani branch of the facial nerve is responsible for carrying taste fibers from the anterior two thirds of the tongue and also provides secretory fibers to submandibular and sublingual salivary glands. The mandibular division of the trigeminal nerve (V3) provides sensory innervation for the anterior two-thirds of the tongue. The glossopharyngeal nerve provides both sensory innervation and taste sensation for the posterior third of the tongue.
