Correct answer: E — Dual antiplatelet therapy for 21 days then monotherapy

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

For high-risk TIA/minor stroke, short-course DAPT (21 days) starting within 24 hours reduces early recurrence; thereafter continue single antiplatelet. Prolonged DAPT (D) increases bleeding; monotherapy (A, B) lacks early combined benefit; no therapy (E) is incorrect.
