Final Answer :
D
Explanation :
The other three veins listed all drain into the hepatic portal vein, which carries nutrient-rich blood from the gastrointestinal tract, pancreas, and spleen to the liver for processing. However, the inferior phrenic vein drains into the inferior vena cava, which carries deoxygenated blood from the lower body back to the heart.
