Answer
(a) Hepatic artery.
The HEPATIC ARTERY brings OXYGENATED blood to the liver, branching from the aorta. Like every other organ, the liver needs oxygen for its own respiration.
The liver is unusual in having TWO blood supplies, and the question is testing whether you can tell them apart: HEPATIC ARTERY — brings OXYGENATED blood from the aorta, for respiration HEPATIC PORTAL VEIN — brings DEOXYGENATED blood from the stomach and intestines, loaded with absorbed FOOD, so that the liver can process it HEPATIC VEIN — the outlet, carrying deoxygenated blood away to the inferior vena cava
THE RULE that settles it without memorising: ARTERIES BRING, VEINS TAKE AWAY. The question asks what SUPPLIES the liver with oxygen, so only an artery can be the answer — which eliminates three of the four options immediately.
Hepatic artery.
