Solution

The correct option is C It systole closes the tricuspid valve
The left ventricle of mammalian heart has the thickest walls due to the efficiency needed to pump blood across the entire body. It recieves oxygenated blood from left atria from the pulmonary vein and aorta carries it forward through the systemic circulation to the entire body. It's systole causes the closure of tricuspid walls to prevent the backflow of blood into the atria.
So, the correct option is 'It systole closes the tricuspid valve'.
