Correct answer: E — Observation for spontaneous re-eruption with clinical and radiographic follow-up

When an intruded primary tooth has its apex displaced labially (away from the developing permanent tooth germ), the risk of damage to the successor is lower. The recommended management is observation for spontaneous re-eruption (which occurs in most cases within 1-6 months). Clinical and radiographic follow-up is essential to monitor for pulp necrosis (discolouration, periapical radiolucency, fistula) and possible re-eruption. If the apex is displaced toward (palatally toward) the permanent tooth germ, extraction is recommended to prevent damage to the successor.
