Correct answer: C — Continuous positive airway pressure and driving safety advice

Symptomatic moderate-to-severe obstructive sleep apnoea with occupational driving risk should be treated with CPAP and given explicit driving safety advice. Daytime hypercapnia is not required for OSA treatment. Oxygen alone does not splint the airway, and sedatives may worsen obstructive events.
