Correct answer: B — Oral amoxicillin 30 mg/kg/day

High-dose oral amoxicillin (30 mg/kg/dose TDS) for 5 days is first-line for AOM in children requiring antibiotics. Not all AOM requires antibiotics; watchful waiting for 48 hours is appropriate for mild AOM in children >6 months without risk factors.
