A. It carries oxygen-poor blood to the tissues: That’s the systemic circuit's function (to deliver oxygen to tissues via arterial blood), so incorrect.
B. It carries oxygen-poor blood to the heart: Venous return from tissues brings oxygen-poor blood back to the heart, but the pulmonary circuit specifically moves blood from the heart to the lungs -so this is misleading/incorrect.
C. It carries oxygen-poor blood from the tissues: The systemic veins do that; the pulmonary circuit carries blood from the heart to the lungs, not directly from tissues.
D. It carries oxygen-poor blood to the lungs: Pulmonary circuit transports deoxygenated blood from the right ventricle to the lungs for oxygenation.
