The pulmonary veins are vessels that deliver oxygen-rich blood from the lungs to the left atrium of the heart. If one of these veins is cut, the hemorrhage would occur into the cavity between the myocardium and epicardium (Option D). Here's why:

A) The fibrous pericardium is the outermost layer of the pericardium (the sac that surrounds the heart), and the parietal pleura is the outer layer of the pleura (the membrane that surrounds the lungs). The pulmonary veins are not located between these two structures.

B) The fibrous pericardium and parietal pericardium are two layers of the pericardium. The pulmonary veins are not located between these two layers, but are instead located within the heart muscle itself.

C) The epicardium is the outermost layer of the heart wall, and the parietal pericardium is the inner layer of the pericardium. The pulmonary veins are not located between these two layers.

D) The myocardium is the middle layer of the heart wall, composed of heart muscle, and the epicardium is the outermost layer of the heart wall. The pulmonary veins run through the myocardium, so if one of these veins were cut, the hemorrhage would occur into the cavity between the myocardium and epicardium.
