Correct answer: D — One root, one canal (Type I Vertucci)
The mandibular canine typically has one root with one canal (Vertucci Type I configuration) in approximately 85% of cases. However, approximately 15% may have a second canal (Type II, III, or IV), making it important to check for additional canals during endodontic treatment. It is the longest tooth in the mouth. The maxillary canine almost always has one root and one canal.
