Detailed explanation-1: -Arteries generally carry oxygenated blood. But pulmonary artery is the artery that transmits deoxygenated blood away from the heart to the organs (like lungs and placenta, respectively) where it gets oxygenated. So, the right option is C i.e. Pulmonary.

Detailed explanation-2: -Arteries are blood vessels that supply oxygen-rich blood to the entire body. They are tube-like vessels. The pulmonary artery is an exception as it carries blood poor in oxygen away from the heart instead of a vein. The pulmonary vein carries oxygen-rich blood to the heart, hence is an exception.

Detailed explanation-3: -A crucial difference is that your pulmonary artery carries oxygen-poor (deoxygenated) blood, while your aorta carries oxygen-rich (oxygenated) blood. In fact, your pulmonary arteries are the only arteries in your body that carry oxygen-poor blood.

Detailed explanation-4: -Arteries normally carry oxygenated blood. However, the pulmonary artery is an exception. It carries deoxygenated blood from the heart to the lungs.

Detailed explanation-5: -The pulmonary veins transport oxygenated blood back to the heart from the lungs, while the pulmonary arteries move deoxygenated blood from the heart to the lungs.)
