Correct answer: D — Rinse the root gently and replant the tooth

A mature avulsed permanent incisor with a short extra-oral dry time and storage in milk should be replanted promptly after gentle rinsing. Scrubbing damages periodontal ligament cells and worsens prognosis. The teaching point is that milk is an acceptable interim medium, but immediate replantation remains the key time-sensitive intervention.
