Verified By Collegedunia
The Correct Option is B
Solution and Explanation
The structure marked as "4" in the image is most likely the urachus. The urachus is a vestigial remnant of the fetal connection between the bladder and the umbilicus. During fetal development, this is part of the allantois, which subsequently becomes obliterated after birth. The urachus ultimately develops into the median umbilical ligament. Therefore, the structure marked "4" develops into the median umbilical ligament.
| Option | Development |
|---|---|
| Medial umbilical ligament | Formed from the obliterated umbilical arteries |
| Median umbilical ligament | Develops from the urachus |
| Meckel's diverticulum | Persistence of the vitelline duct |
| Ligamentum teres | Derived from the obliterated umbilical vein |
The correct answer is: Median umbilical ligament.
