Which of the following is the most common congenital heart defect?

Which of the following statements are consistent with the response of baroreceptors to high blood pressure? I.The cardioregulatory center slows the heart rate. II.The carotid and aortic baroreceptors transmit impulses through the glossopharyngeal and vagus nerves. III.Impulses are sent to the brain's vasomotor and cardioregulatory centers.
