Correct answer: C — Maxillary central incisor
The maxillary central incisor almost invariably has a single root with a single canal (Vertucci Type I in >99% of cases). It has the most predictable and straightforward root canal anatomy of any permanent tooth, making it ideal for endodontic access teaching. The root is conical and straight with a rounded cross-section. The pulp chamber and canal are wide in young teeth, narrowing with age due to secondary dentin deposition.
