Answer:
a The pulmonary artery carries deoxygenated blood.
Explanation:
This is the the only artery that transports deoxygented blood in mammals. specifically it carry deoxgenated blood from the the atria to the pulmonary circulation. That is to the lungs for the exchange of the C02 in the deoxygenated blood with oxygen in the lungs.
The blood thus become oxygenated,and therefore return through the pulmonary veins to the left ventricle.
From the left ventricle ,through ventricular systole,blood is empty into the aorta through the aortic valves into the systemic circulation.
Although,they carry blood away from the heart,but the blood is de oxygenated instead of the usual oxygenated by arteries,They are still regarded as arteries because of convey of blood away from the heart,a typical role of arteries
