## **Core Concept**
The Frank Breech is a type of fetal presentation that occurs during pregnancy and labor. It is characterized by the fetal position where the buttocks are presenting first in the birth canal. Understanding the specific positioning of the fetus in a Frank Breech is crucial for obstetric management.

## **Why the Correct Answer is Right**
In a Frank Breech, the fetal thighs are flexed at the hip, bringing the knees up towards the chest, while the legs are extended downward. This positioning is what allows for the buttocks to present first. Therefore, the description that matches this positioning is: **thigh flexed, knee extended**.

## **Why Each Wrong Option is Incorrect**
- **Option A: Thigh extended, leg extended** - This does not accurately describe a Frank Breech. In a Frank Breech, the thighs are flexed, not extended.
- **Option C: Both are flexed** - While the thighs are flexed in a Frank Breech, the knees are extended, not flexed.
- **Option D: Buddha's attitude** - This term refers to a different fetal position, often described in the context of a different type of breech presentation or a specific posture of the fetus.
- **Option E: Common in primi** - While primigravidas (women pregnant for the first time) can have breech presentations, the statement does not specifically describe the fetal positioning in a Frank Breech.

## **Clinical Pearl / High-Yield Fact**
A key clinical pearl is that Frank Breech presentations are more common in preterm infants and in multiparous women. However, the specific positioning (thighs flexed, knees extended) is what defines a Frank Breech, making option B a critical fact to remember.

## **Correct Answer:** B. thigh flexed, knee extended
