Correct Answer � B Explanation |

Option B: Ligamentum teres
Peritoneal ligaments:
- Gastrosplenic ligament: It extends from the spleen's hilum to the stomach's greater curvature. It contains short gastric and left gastroepiploic vessels.
- Lienorenal ligament: It extends from the spleen's hilum to the left kidney's anterior surface. It contains splenic vessels and the tail of the pancreas. It develops from the dorsal mesogastrium.
- Gastrophrenic ligament: It connects the greater curvature of the stomach to the diaphragm. It develops from the dorsal mesogastrium.
- Phrenicocolic ligament connects the left colic (splenic) flexure to the diaphragm. It supports the anterior border of the spleen.
- Falciform ligament: It demarcates the right and left lobes of the liver. It contains ligamentum teres (remnant of the left umbilical vein) and paraumbilical vein. It develops in the ventral mesogastrium (ventral part).
- Coronary ligaments: It contains superior and inferior layers which connect the liver to the diaphragm and encloses the triangular 'bare area of the liver.
- Triangular ligaments (a right and a left): These connect the right and left lobes of the liver to the diaphragm. It develops from ventral mesogastrium.
Option A: Ligamentum venosum
- Falciform ligament demarcates the right and left lobes of the liver.
- It contains ligamentum teres (remnant of the left umbilical vein) and paraumbilical vein.
- The ligamentum venosum, also known as Arantius' ligament, is the fibrous remnant of the ductus venosus of fetal circulation.
Option C: Lienorenal ligament
- Lienorenal ligament extends from the spleen's hilum to the left kidney's anterior surface. It contains splenic vessels and the tail of the pancreas. It develops from the dorsal mesogastrium.
Option D: Gastrophrenic ligament
- Gastrophrenic ligament connects the greater curvature of the stomach to the diaphragm. It develops from the dorsal mesogastrium.
