The correct answer is based on the primary function of the right ventricle during the cardiac cycle. When the right ventricle contracts, a process known as systole occurs, which results in the muscular walls of the ventricle tightening and forcing blood into the pulmonary artery.

The pulmonary artery is responsible for transporting deoxygenated blood from the right ventricle to the lungs, where carbon dioxide is exchanged for oxygen. This step is crucial for the oxygenation of blood, allowing it to become rich in oxygen before being circulated to the rest of the body.

In contrast, the other options do not accurately represent the physiological function of the right ventricle during contraction. Blood flowing to the left atrium occurs as part of the systemic circulation, particularly from the pulmonary veins after blood has been oxygenated in the lungs. Blood being delivered to the body is the responsibility of the left ventricle, which sends oxygenated blood throughout the systemic circulation. On the other hand, the right atrium serves as the chamber that receives blood from the body and passes it to the right ventricle; it does not store blood during the contraction of the right ventricle.

Understanding these dynamics reinforces the role of the right ventricle in
