Correct answer: C — Allow spontaneous re-eruption with review

Many intruded primary incisors with the apex displaced away from the permanent successor are observed for spontaneous re-eruption with close follow-up. Replantation is inappropriate for primary teeth and may damage the permanent successor. The pearl is that the direction of displacement matters more than the dramatic appearance of the intrusion.
