Correct answer: B — Regenerative endodontic procedure when feasible

In a necrotic immature permanent tooth with open apex and thin walls, regenerative endodontic treatment may allow continued root development when case factors permit. Conventional obturation in an open apex is technically difficult and does not promote root maturation. The pearl is that apexification can close an apex, but regeneration is preferred in many suitable immature cases because it may strengthen the root over time.
