The correct option is D Begins at the hind end of abdomen
The inferior or posterior vena cava runs posterior or behind the abdominal cavity. The inferior vena cava is the result of two major leg veins coming together. These leg veins are called iliac veins. The iliac veins come together at the fifth lumbar vertebra. Once the iliac veins have merged, the inferior vena cava begins to transport blood to the heart.
