Best answer

Answer: 3. Intestine

Key idea: The hepatic portal vein carries nutrient-rich blood from the digestive organs to the liver.

Of the options, the intestine is the one that drains into it, bringing absorbed food. The kidneys drain through the renal vein, and the heart receives blood but does not send it to the liver by this vein. Answer: (3).
