Detailed explanation-1: -the tricuspid valve, located between the right atrium and the right ventricle; the pulmonary valve, between the right ventricle and the pulmonary artery; the mitral valve, between the left atrium and left ventricle; and. the aortic valve, between the left ventricle and the aorta.

Detailed explanation-2: -The valves prevent blood from flowing backward. The heart has four valves. The tricuspid valve separates the right atrium and right ventricle. The mitral valve separates the left atrium and left ventricle.

Detailed explanation-3: -The correct option is C Tricuspid. Tricuspid valve is present between the right atrium and right ventricle. It has three flaps that open and close, allowing blood to flow from the right atrium to the right ventricle in our heart and preventing blood from flowing backward.

Detailed explanation-4: -Tricuspid valve: This valve has three leaflets. They allow blood to flow from the right atrium to the right ventricle. They also prevent blood from flowing backward from the right ventricle to the right atrium.
