None of the above

Detailed explanation-1: -When the left ventricle contracts, the mitral valve closes and the aortic valve opens. This is so blood flows into the aorta and out to the rest of the body. While the left ventricle is relaxing, the right ventricle also relaxes. This causes the pulmonary valve to close and the tricuspid valve to open.
Detailed explanation-2: -The mitral valve connects the left atrium (LA) and the left ventricle (LV). The mitral valve opens during diastole to allow the blood flow from the LA to the LV. During ventricular systole, the mitral valve closes and prevents backflow to the LA.
Detailed explanation-3: -When the two atrium chambers contract, the tricuspid and mitral valves open, which both allow blood to move to the ventricles. When the two ventricle chambers contract, they force the tricuspid and mitral valves to close as the pulmonary and aortic valves open.
