Correct answer: D — Treat fever aggressively, monitor rhythm and obtain urgent cardiology advice

Explanation lettering: C = shown as A · E = shown as C · A = shown as E

D is correct. Fever can unmask or worsen the Brugada substrate; aggressive antipyresis, continuous rhythm monitoring and urgent cardiology input are appropriate. A misses a recognised arrhythmic trigger. B sodium-channel blockade can exacerbate Brugada physiology. C exercise testing is not an acute febrile-risk intervention. E adenosine does not treat or safely risk-stratify this ventricular arrhythmia syndrome.
