A.

coronary artery

Coronary arteries are the blood vessels that supply the heart muscle (cardiac tissue) with blood rich in oxygen.

Coronary sinus is a collection of veins joined together to form a large vessel that collects blood from the heart muscle. It carries less oxygenated blood to the right atrium as do the superior and inferior vena cavae.

Pulmonary veins are the veins that transfer oxygenated blood from the lungs to the heart. The largest pulmonary veins are the four main pulmonary veins, two from each lung that drain into the left atrium of the heart.
