PATHOLOGY

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: -An easy mnemonic is “A for ‘artery’ and ‘away’ (from the heart).” (The exceptions to this general rule are the pulmonary vessels. 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.)

Detailed explanation-3: -The first and most important difference between the two is that all arteries carry blood away from the heart, and all veins carry blood to the heart from outlying areas. Most arteries carry oxygenated blood, and most veins carry deoxygenated blood; the pulmonary arteries and veins are the exceptions to this rule.
