**Question:** Least chances of cord prolapse are seen in?

**Core Concept:** Cord prolapse is a rare but serious complication that occurs during childbirth, where part of the umbilical cord passes through the cervix and is presented alongside the fetus. Cord prolapse can lead to fetal distress and hypoxia due to compression of the cord.

**Why the Correct Answer is Right:** The correct answer is **C. Forceps delivery**. Forceps delivery is a method of assisted vaginal delivery using forceps to turn and deliver the fetus. It is less likely to cause cord prolapse compared to other methods like vacuum extraction or cesarean section. The forceps allow for better control and positioning of the fetus, reducing the risk of cord prolapse.

**Why Each Wrong Option is Incorrect:**

A. **Vacuum extraction**: This method involves suctioning the fetus out of the birth canal. However, the high-tension force applied during vacuum extraction can lead to increased risk of cord prolapse due to the abrupt and uncontrolled delivery of the fetus.

B. **C-section**: While cesarean section is a safe method to deliver a fetus, it does not address the risk of cord prolapse. Cesarean section is an emergency procedure performed when other methods fail or are deemed unsafe.

C. **Forceps delivery**: As explained above, forceps delivery is less likely to cause cord prolapse due to better control and positioning of the fetus during delivery.

D. **Spontaneous labor**: Not choosing a specific method of delivery does not guarantee the least chances of cord prolapse. The risk of cord prolapse remains present in spontaneous labor, unless proper surveillance and timely intervention are employed by the medical team.

**Clinical Pearl:**

In clinical practice, choosing the appropriate method of delivery (forceps or vacuum extraction) based on the obstetric scenario significantly reduces the risk of cord prolapse. Timely recognition and intervention during delivery significantly decreases the risk of cord prolapse regardless of the method used.

**Correct Answer Explanation:** Cord prolapse is least likely to occur in a case of **forceps delivery**. Forceps allow for better control and positioning of the fetus during delivery, reducing the risk of cord prolapse. Timely recognition and appropriate intervention by the medical team further decrease the risk of this complication.
