The correct Answer is:
To determine which of the following options carries deoxygenated blood only, we can analyze each option step by step: ### Step 1: Understand the role of arteries and veins - **Arteries** typically carry oxygenated blood away from the heart to the body, while **veins** carry deoxygenated blood back to the heart. ### Step 2: Analyze the options - **A. Carotid artery**: This artery carries oxygenated blood from the heart to the head and neck. Therefore, it does not carry deoxygenated blood. - **B. Pulmonary artery**: This artery is unique because it carries deoxygenated blood from the heart to the lungs for oxygenation. Thus, it carries deoxygenated blood only. - **C. Pulmonary vein**: This vein carries oxygenated blood from the lungs back to the heart. Therefore, it does not carry deoxygenated blood. - **D. Aorta**: The aorta is the largest artery in the body and carries oxygenated blood from the heart to the rest of the body. Thus, it does not carry deoxygenated blood. ### Step 3: Conclusion After analyzing all the options, we find that the only vessel that carries deoxygenated blood only is the **pulmonary artery**. ### Final Answer: **B. Pulmonary artery** ---
