Which of the Following Statements BEST Explains How Myocardium Tissue

Which of the following statements BEST explains how myocardium tissue perfusion occurs primarily during periods of muscle relaxation (diastole) ?

A) All fluids follow the path of least resistance and flow from higher to lower pressure.
B) The right ventricle has a lower pressure than the left ventricle during systole resulting in less difference in blood flow in the right coronary artery between systole and diastole.
C) During diastole,full coronary arteries create high pressures,driving blood into the myocardium when intramyocardial pressure drops.
D) When the aortic valve closes,pressure is transmitted through dilated Valsalva sinuses to openings of coronary arteries.
