Final answer:
The left ventricle of the heart contains oxygenated blood, while the right ventricle contains deoxygenated blood.
Step-by-step explanation:
The left ventricle of the heart pumps oxygenated blood to the rest of the body through the aorta. On the other hand, the right side of the heart pumps deoxygenated blood to the lungs through the pulmonary artery.
This means that oxygenated blood is located in the left ventricle (A) while deoxygenated blood is located in the right ventricle (B).
