Correct answer: E — Deepen anaesthesia with propofol 0.5 mg/kg IV

Complete laryngospasm unresponsive to jaw thrust/CPAP: first try deepening anaesthesia with small-dose IV propofol (0.5-1 mg/kg), which relaxes laryngeal muscles without suxamethonium risks. If this fails, suxamethonium 0.5-1 mg/kg IV is definitive. Propofol tried first to avoid depolarising NMB risks.
