Correct answer: B — Immediately at the scene

Option A is correct. An avulsed permanent tooth should be replanted immediately at the scene when feasible, because prolonged extra-oral storage increases the risk of resorption and reduces tooth longevity. The tooth should be handled by its crown; if dirty, it may be gently rinsed in milk, saline or the patient's saliva before replantation. If immediate replantation is impossible, it should be kept moist in milk, saliva or saline while emergency dental care is obtained. Waiting until clinic arrival (B) or radiographic examination (C) creates avoidable delay. Storage for 24 hours (D) is not the ideal approach and substantially worsens prognosis. Non-replantation (E) applies to avulsed primary teeth, not the permanent incisor described.
