Correct answer: B — Glossopharyngeal nerve (CN IX)
Preganglionic parasympathetic fibres from CN IX (via the lesser petrosal nerve) synapse in the otic ganglion. Postganglionic fibres then hitchhike on the auriculotemporal nerve (branch of V3) to reach the parotid gland, stimulating serous secretion. CN VII provides parasympathetic supply to the submandibular and sublingual glands via the submandibular ganglion.
