Reveal the answer and explanation

Correct answer: A — Delay 1-3 days for minor stroke

Secondary prevention in AF after minor stroke often starts anticoagulation within 1-3 days if no hemorrhage and imaging stable; longer delays apply to larger infarcts/hemorrhagic risk. Antiplatelets alone are insufficient.
