Correct answer: C — Fifteen milligrams twice daily for 21 days, then 20 mg once daily

Acute DVT or PE treatment uses rivaroxaban 15 mg twice daily for 21 days, followed by 20 mg once daily when renal function permits. Both 15 mg and 20 mg doses are taken with food. Treatment duration depends on provoking factors and recurrence risk.
