C. Renal vein
D. Caudal

Answer

To determine which artery supplies blood to the diaphragm, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Diaphragm**: The diaphragm is a dome-shaped muscular structure that separates the thoracic cavity from the abdominal cavity. It plays a crucial role in respiration.

2. **Function of the Diaphragm**: The diaphragm contracts during inspiration, increasing the volume of the thoracic cavity and allowing air to be drawn into the lungs. It works in conjunction with the intercostal muscles.

3. **Blood Supply to the Diaphragm**: The diaphragm receives its blood supply primarily from the **phrenic artery**. The term "phrenic" is associated with the diaphragm.

4. **Additional Blood Supply**: While the phrenic artery is the main supplier, the diaphragm may also receive some blood from the inferior phrenic arteries, which branch off from the abdominal aorta.

5. **Conclusion**: Therefore, the artery that primarily supplies blood to the diaphragm is the **phrenic artery**.

### Final Answer:
The artery that supplies blood to the diaphragm is the **phrenic artery**.
