The correct answer is the Pulmonary artery.

Explanation:

1. Role of Blood Vessels: In the circulatory system, arteries are primarily responsible for carrying blood away from the heart. However, not all arteries carry oxygenated blood.

2. Pulmonary Artery Function: The pulmonary artery is unique because it carries deoxygenated blood from the right ventricle of the heart to the lungs. In the lungs, the blood releases carbon dioxide and absorbs oxygen, becoming oxygenated.

3. Other Arteries:

   • Carotid artery: Carries oxygenated blood to the brain.
   • Facial artery: Supplies oxygenated blood to the face.
   • Renal artery: Delivers oxygenated blood to the kidneys.

The pulmonary artery's function of transporting deoxygenated blood distinguishes it from these other arteries, which carry oxygenated blood. Thus, the pulmonary artery is the only artery that carries deoxygenated blood.
