## **Core Concept**
The expectant line of management in placenta previa involves a conservative approach aimed at delaying delivery until fetal maturity is achieved or until a suitable gestational age is reached for delivery, usually beyond 37 weeks of gestation. This approach is chosen for patients who are not actively bleeding and are stable. However, certain conditions may contraindicate this approach.

## **Why the Correct Answer is Right**
The correct answer, , indicates a condition where expectant management is contraindicated. Typically, active bleeding or severe hemorrhage is a contraindication for expectant management because it necessitates immediate intervention to stabilize the mother and deliver the baby. This condition requires prompt delivery, often by cesarean section, to prevent maternal and fetal morbidity and mortality.

## **Why Each Wrong Option is Incorrect**
- **Option A:** This option is incorrect because, without specifying the condition, it's hard to judge its relevance. However, if it represents a stable condition or a minor issue, expectant management might still be considered.
- **Option B:** Similarly, this option is incorrect as it might represent a scenario where expectant management could still be safely employed, depending on the specifics of the condition.
- **Option C:** This option is incorrect because it is the correct answer, making the others incorrect by default.

## **Clinical Pearl / High-Yield Fact**
A key clinical pearl is that in cases of placenta previa with active bleeding or a history of significant bleeding, immediate delivery is often required, making expectant management risky. The management approach must be tailored to the individual patient's condition, considering the stability of both the mother and the fetus.

## **Correct Answer:** . Active bleeding/ severe hemorrhage.
