The caudate lobe has a dual portal venous supply from both the right and left portal veins. Its position on the liver’s posterior superior aspect near the IVC allows small portal branches to originate from each main portal division, feeding the lobe from both sides. This makes sense given its anatomical bridge between the right and left lobes, so it is not limited to a single portal vein trunk. The other options would imply the caudate lobe receives input from only one side or from the trunk as a whole, which does not fit its dual-supply anatomy.
