Which of the following is the STRONGEST risk factor for placenta previa?
- A Chronic hypertension
- B Previous cesarean section ✓
- C Maternal age below 25 years
- D Primigravida status
Correct answer: B. Previous cesarean section
Explanation
Previous cesarean section is one of the strongest risk factors for placenta previa due to scarring of the uterine cavity altering placental implantation. Risk increases with the number of prior cesarean sections. Chronic hypertension is more associated with abruption. Young maternal age and primigravida status are actually protective, not risk factors.
