Answer: 4. Vena cava

Key idea: In a frog, veins called the vena cavae (precaval and postcaval) bring deoxygenated blood from the body to the sinus venosus and then the right atrium.

The aorta and pulmonary artery carry blood away from the heart, and the pulmonary vein carries oxygenated blood from the lungs. So the answer is vena cava.
