Correct answer: B — Posterior one-third

CN IX provides both taste and general sensation to the posterior one-third of the tongue. It also provides sensation to the oropharynx / tonsillar fossa / and middle ear. The anterior two-thirds receives taste via CN VII (chorda tympani) and general sensation via V3 (lingual nerve).
