Correct answer: A — Furcation probing with periapical/bitewing assessment

Through-and-through furcation involvement is assessed clinically with a curved probe and radiographically with appropriate intraoral images. Vitality testing helps exclude endodontic contribution but cannot grade furcation destruction alone. The pearl is that furcation anatomy strongly affects prognosis and treatment planning for molars.
