Verified step by step guidance

1. Understand the role of the inferior vena cava: It is a large vein that carries deoxygenated blood from the lower and middle body into the heart.
2. Identify the location and function of each vein option: Hepatic veins, Coronary sinus, Pulmonary veins, and Jugular veins.
3. Hepatic veins: These veins drain blood from the liver and empty directly into the inferior vena cava.
4. Coronary sinus: This vein collects blood from the heart muscle and drains into the right atrium, not the inferior vena cava.
5. Pulmonary veins: These veins carry oxygenated blood from the lungs to the left atrium, not the inferior vena cava. Jugular veins: These veins drain blood from the head and neck into the superior vena cava, not the inferior vena cava.
