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. Fibrinogen:$\newline$ - Fibrinogen is a plasma protein that plays a crucial role in blood clotting.$\newline$ - This matches with ii. Blood clotting.$\newline \bullet$b. Globulin:$\newline$ - Globulins are a group of proteins in the blood plasma that are involved in the immune response and defense mechanisms.$\newline$ - This matches with iii. Defense mechanism.$\newline \bullet$c. Albumin:$\newline$ - Albumin is the most abundant plasma protein and is primarily responsible for maintaining osmotic balance in the blood.$\newline$ - This matches with i. Osmotic balance.$\newline$Now, let's match the items from Column I with Column II:$\newline a \rightarrow ii, b \rightarrow iii, c \rightarrow i \newline$This corresponds to Option 4.
