As per standard obstetric definitions followed in Indian examinations, primary postpartum hemorrhage following a vaginal delivery is defined as blood loss exceeding:

• A 200 mL within 24 hours of delivery
• B 1000 mL within 6 hours of delivery
• C 500 mL within 24 hours of delivery ✓
• D 500 mL within 6 weeks of delivery

Explanation

Primary PPH is blood loss of more than 500 mL within 24 hours of birth (more than 1000 mL after cesarean delivery); secondary PPH is abnormal bleeding from 24 hours to 12 weeks postpartum. Option D describes the time window of secondary PPH, not primary, and option B applies the cesarean threshold incorrectly to vaginal birth.
