Correct answer: B — Refer to the prescriber to consider a direct oral anticoagulant

Older age and hypertension increase thromboembolic risk in atrial fibrillation. Anticoagulation is usually indicated when stroke risk is raised, with DOACs commonly used for non-valvular AF. Aspirin or clopidogrel are not appropriate substitutes for anticoagulation for AF stroke prevention.
