D. No, the septum keeps the oxygen-rich and oxygen-poor blood separate.
The heart's right side handles deoxygenated blood to the lungs and the left side pumps oxygenated blood to the body; the interatrial and interventricular septa (and valves) prevent mixing in a normal heart. (Congenital septal defects or fetal shunts are exceptions.)
