Answer

**Step-by-Step Solution:**

1. **Understanding Arteries**: Arteries are blood vessels that carry blood away from the heart to various parts of the body. They are characterized by thick walls and a narrow lumen.

2. **Characteristics of Arteries**: The walls of arteries are thick because they need to withstand high blood pressure. The blood is pumped from the heart into the arteries, which requires the walls to be strong and elastic.

3. **Comparison with Other Blood Vessels**: Unlike arteries, veins carry blood back to the heart. Veins have thinner walls and a wider lumen because they operate under lower blood pressure.

4. **Identifying the Correct Definition**: Given the options, the one that best defines arteries is the one that states they carry blood away from the heart.

5. **Conclusion**: Therefore, the correct answer to the question "Arteries are best defined as vessels which..." is option D: "Arteries carry blood away from the heart to different organs."
