Correct answer: C — Handle gently, prevent further heat loss and initiate active core rewarming with transfer to an extracorporeal-capable centre if instability persists

Moderate to severe accidental hypothermia requires gentle handling to reduce arrhythmia risk, active rewarming and triage to extracorporeal rewarming when severe instability or cardiac arrest is present.
