• D. $\begin{array}{ccc}\text{A}& \text{B}& \text{C}\\ \text{(ii)}& \text{(i)}& \text{(iii)}\end{array}$

Answer 1

The correct option is A $\begin{array}{ccc}\text{A}& \text{B}& \text{C}\\ \text{(iii)}& \text{(i)}& \text{(ii)}\end{array}$

The opening between the right atrium and the right ventricle is guarded by a valve formed of three muscular flaps or cusps, the tricuspid valve, whereas a bicuspid or mitral valve guards the opening between the left atrium and the left ventricle. The openings of the right and the left ventricles into the pulmonary artery and the aorta respectively are guarded by the semilunar valves. The valves in the heart allows the flow of blood only in one direction, i.e., from the atria to the ventricles and from the ventricles to the pulmonary artery or aorta. These valves prevent any backward flow of blood.
