Why must the muscles of the left ventricle be the strongest ones in the heart?
 
  a. The mitral (bicuspid) valve is larger than the aortic valve.
  b. The left ventricle receives blood under high pressure from the pulmonary system.
  c. The pressure in the aorta is higher than the pressures elsewhere in the circulatory system.
  d. Blood in the left ventricle is oxygenated, making it thicker and harder to move than deoxygenated blood.
