a. The volume of blood pumped out by the Rt and Lt ventricles is same.

b. The volume of blood pumped out by the Rt and Lt ventricles is different

c. The volume of blood received by each atrium is different

d. The volume of blood received by the aorta and pulmonary artery is different

correct option – ( a )

explanation – in a cardiac cycle each ventricle pumps approximately 70mL of blood . Thus both ventricles pump same amount of blood

hence correct answer is – The volume of blood pumped out by the Rt and Lt ventricles is same
