To solve this problem, we need to match the items in Column I with the appropriate descriptions in Column II. Let's analyze each item:$\newline \bullet$a. Tricuspid valve:$\newline$ - The tricuspid valve is located between the right atrium and the right ventricle.$\newline$ - This matches with iii.$\newline \bullet$b. Bicuspid valve:$\newline$ - The bicuspid valve, also known as the mitral valve, is located between the left atrium and the left ventricle.$\newline$ - This matches with i.$\newline \bullet$c. Semilunar valve:$\newline$ - The semilunar valves are located between the ventricles and the arteries. Specifically, the pulmonary semilunar valve is between the right ventricle and the pulmonary artery.$\newline$ - This matches with ii.$\newline$Now, let's match the items from Column I with Column II:$\newline a \rightarrow iii, b \rightarrow i, c \rightarrow ii \newline$This corresponds to Option 3.
