which vessel of the pulmonary circuit is labeled a in this picture?
inferior lobar artery
superior lobar artery
right pulmonary artery
pulmonary trunk
middle lobar artery

Explanation:

To determine the vessel labeled A, we analyze the pulmonary circuit anatomy. The right pulmonary artery carries deoxygenated blood from the heart to the right lung. The labeled A vessel connects to the right lung's vascular network, matching the right pulmonary artery's role. Other options (inferior/superior/middle lobar arteries) are smaller, branch - like, and the pulmonary trunk splits into left and right pulmonary arteries, so A is the right pulmonary artery.

Answer:

C. Right pulmonary artery
