Correct answer: B — Start ventilation with oxygen and CPR, then attach the AED promptly

Drowning arrest is primarily hypoxic, so early ventilation with oxygen plus chest compressions is essential. AED use should not be delayed, but defibrillation does not replace ventilation in hypoxic arrest. Attempts to drain water waste time and may cause aspiration or injury.
