Answer 1

Right choice is (c) Blood from pulmonary vein flows into the right atrium

Easy explanation: In the joint diastole state, all four chambers of the heart are relaxed. The tricuspid and bicuspid valves are open while the semilunar valves are closed. Blood from pulmonary vein flows into the left ventricle.
