The question asks about the hepatic artery’s blood in relation to delivering to the liver. 
Option 1: Oxygenated. This aligns with anatomy: the hepatic artery carries oxygen-rich blood from the heart (systemic circulation) to the liver, providing the oxygen necessary for hepatocytes. 
Option 2: Deoxygenated. This is incorrect because the hepatic artery’s flow is oxygenated, not deoxygenated; the deoxygenated blood from the gut and spleen reaches the liver via the hepatic portal vein, not the hepatic artery. 
Option 3: Nutrient-rich. While portal venous blood is rich in nutrients absorbed from the gut, the hepatic artery does not deliver nutrient-rich blood; it delivers oxygenated blood. Thus, this option mischaracterizes the arterial blood’s primary feature. 
Option 4: Partially oxygenated. This is inaccurate because the hepatic artery delivers blood that is largely fully oxygenated; there isn’t a partial oxygenation state typical for this arterial supply. The distinction between arterial oxygen content and portal venous content is important here.
