Question

Match the items given in Column I with those in Column II and select the correct option given below :

Column I		Column II
a.	Fibrinogen	i.	Osmotic balance
b.	Globulin	ii.	Blood clotting
c.	Albumin	iii.	Defence mechanism

• A. a-iii, b-ii, c-i
• B. a-i, b-iii, c-ii
• C. a-i, b-ii, c-iii
• D. a-ii, b-iii, c-i

Answer 1

The Correct Option is D

To solve this question, we need to correctly match the biological terms provided in Column I with their appropriate functions listed in Column II.

Let's analyze each component:

1. Fibrinogen: This is a key protein involved in blood clotting. It is converted into fibrin during the clotting process, which helps to stop bleeding by forming a mesh that traps blood cells. Thus, it matches with Option ii. Blood clotting.
2. Globulin: Globulins are a group of proteins in the blood serum that serve various functions, including roles in the immune system as antibodies. Thus, they are primarily associated with the body's defense mechanisms. So, it matches with Option iii. Defence mechanism.
3. Albumin: This is the most abundant protein in the blood plasma and plays a crucial role in maintaining the osmotic balance in the body by regulating the blood volume and pressure. Thus, it matches with Option i. Osmotic balance.

Therefore, the correct matching is:

• a - ii: Fibrinogen - Blood clotting
• b - iii: Globulin - Defence mechanism
• c - i: Albumin - Osmotic balance

The correct option is a-ii, b-iii, c-i.
