Correct answer: B — Direct oral anticoagulant (DOAC)

Explanation lettering: D = shown as B · E = shown as C · B = shown as D · C = shown as E

The 2024 ESC AF Guidelines recommend DOACs as first-line anticoagulation for stroke prevention in non-valvular AF (Class I, LOE A). Warfarin (A) is reserved for mechanical valves or moderate-severe mitral stenosis. LMWH (C) is not for long-term stroke prevention. Aspirin (D) and DAPT (E) are not recommended for stroke prevention in AF.
