Answer:

Deoxygenated.

Explanation:

The first thing to remember is that all the veins in our body except the pulmonary vein and the umbilical vein carry deoxygenated blood.

The second thing to remember is that the hepatic portal vein carries blood which contains dissolved food molecules in it. It carries blood between the small intestine and liver, so all the oxygen would have been used up in the small intestine to absorb nutrients from food.

Therefore, the blood arriving at the liver from the hepatic portal vein is deoxygenated.
