The incidence of breech at term is NOT RELATED-GYN

## Core Concept
The incidence of breech presentation at term refers to the percentage of pregnancies where the fetus is in a breech position (feet or buttocks down) at the time of delivery. This is an important concept in obstetrics as it affects delivery management and outcomes. The normal incidence of breech presentation at term is around 3-4%.

## Why the Correct Answer is Right
The correct answer, which is 3-4%, is right because this is the commonly cited incidence of breech presentation at term in the medical literature. Breech presentations are more common in preterm pregnancies but decrease as the pregnancy advances towards term. Various factors contribute to breech presentation at term, including uterine anomalies, multiple gestations, and polyhydramnios.

## Why Each Wrong Option is Incorrect
- **Option A:** This option is incorrect because it does not accurately represent the known incidence of breech presentation at term.
- **Option B:** This option is incorrect for similar reasons; it does not align with the established medical data regarding breech incidence.
- **Option D:** This option suggests a much higher incidence than what is typically reported in medical literature.

## Clinical Pearl / High-Yield Fact
A key point to remember is that the majority of breech presentations at term are diagnosed prenatally, and the management often involves external cephalic version (ECV) or planning for a cesarean delivery if the breech position persists. The risk factors for breech presentation include prior breech presentation, uterine anomalies, and multiple gestations.

## Correct Answer: B. 3-4%
