Which branch of CN V carries parasympathetic fibers to the parotid gland?

Explanation:
Parasympathetic fibers that stimulate the parotid gland ride along the auriculotemporal nerve. The preganglionic parasympathetics come from the glossopharyngeal nerve and synapse in the otic ganglion; the postganglionic fibers then hitchhike with the auriculotemporal branch of the mandibular division of the trigeminal nerve (V3) to reach the parotid. The other branches listed are mainly sensory branches of V3 and do not carry these postganglionic parasympathetic fibers to the parotid (lingual carries fibers to the tongue and submandibular/sublingual region via chorda tympani, while buccal and inferior alveolar are primarily sensory or motor to other targets).
