Correct answer: D — Maxillary first premolar

The maxillary first premolar most commonly has two roots (buccal and palatal), occurring in approximately 60-70% of cases. It may also present as single-rooted (~30%) or rarely three-rooted. The mandibular first premolar is typically single-rooted. Understanding root morphology is critical for endodontic treatment, extraction planning, and periodontal assessment.
