From which vessel does the common iliac artery arise?

• A. Abdominal aorta
• B. Inferior vena cava
• C. Renal artery
• D. Celiac trunk

Answer: (A)

The common iliac arteries originate at the bifurcation of the abdominal aorta. As the aorta travels through the abdomen, it splits into left and right common iliac arteries, which then give rise to the internal and external iliac branches to supply the pelvis and lower limbs. The inferior vena cava is a vein, not a source of arterial branches. The renal arteries are separate arterial branches to the kidneys, and the celiac trunk is a proximal branch supplying the upper abdominal organs.
