Correct answer: D — Immediate descent or evacuation with oxygen and dexamethasone if available

Ataxia and confusion at altitude indicate high altitude cerebral oedema until proved otherwise. Descent/evacuation and oxygen are the definitive priorities, with dexamethasone as adjunct where available. Continuing ascent or waiting risks coma and death.
