## Core Concept
The cardinal movements of labor refer to the specific sequence of movements that the fetal head undergoes as it passes through the birth canal during delivery. These movements are essential for the safe and successful vaginal delivery of the baby. Understanding the correct sequence of these movements is crucial for obstetricians and healthcare providers.

## Why the Correct Answer is Right
The correct sequence of cardinal movements during normal labor is:
1. **Engagement**: The fetal head moves down into the pelvis.
2. **Descent**: The fetal head continues to move down through the pelvis.
3. **Flexion**: The fetal head flexes its chin to its chest to navigate through the pelvis more easily.
4. **Internal Rotation**: The fetal head rotates to align with the pelvis.
5. **Extension**: The fetal head extends as it moves through the vaginal outlet.
6. **Restitution**: The fetal head rotates back to its original position.
7. **External Rotation (or Rotation)**: The fetal head rotates to align with the shoulders.
8. **Expulsion**: The final movement where the baby is delivered.

## Why Each Wrong Option is Incorrect
- **Option A:** This option does not accurately represent the sequence of cardinal movements.
- **Option B:** Similarly, this option is incorrect as it does not follow the established sequence of movements during labor.
- **Option D:** This option is also incorrect for the same reason, not adhering to the recognized order of cardinal movements.

## Clinical Pearl / High-Yield Fact
A key point to remember is that these movements are sequential and each movement facilitates the next one, ensuring the baby navigates through the birth canal safely. Understanding and recognizing the normal progression of labor is vital for the management of normal and abnormal labor.

## Correct Answer: C.
