Answer: 3. more than that in the pulmonary vein.

The pulmonary artery carries blood from the right ventricle at a pressure much higher than the pulmonary vein, since pressure falls along the circuit.

1, 2: Aortic and carotid pressure (systemic, left ventricle) is higher than pulmonary artery pressure.
4: Venae cavae pressure is nearly zero, so it is lower than the pulmonary artery.
