Correct answer: B — Nasopalatine nerve and associated sphenopalatine–greater palatine arterial branches

The incisive canal contains the nasopalatine nerve and an arterial anastomosis between terminal branches of the sphenopalatine and greater palatine arteries. Therefore, B is correct. Option D is the most plausible distractor because the greater palatine artery contributes to the anastomosis; however, the greater palatine nerve runs anteriorly on the hard palate rather than through the incisive canal. The mental and inferior alveolar neurovascular bundles are associated with the mandible and the mental or mandibular canals. The infraorbital nerve and vessels pass through the infraorbital groove, canal and foramen, not the incisive canal.
