which of the following blood plasma proteins is correctly matched with its function

Options

A. Albumin : Maintain water level and osmolarity of blood
B. Globulin : Helps to provide antibody mediated immunity (AMl)
C. Fibrinogen : Helps in coagulation of blood .
D. All of these

Answer

To solve the question regarding which blood plasma protein is correctly matched with its function, we will analyze each option provided:

### Step-by-Step Solution:

1. **Identify the Blood Plasma Proteins and Their Functions**:
- We have four options to evaluate: Albumin, Globulin, Fibrinogen, and the option that includes all of these.

2. **Evaluate the First Option: Albumin**:
- **Function**: Maintain water level and osmolarity of the blood.
- **Analysis**: Albumin is indeed responsible for maintaining osmotic pressure and transporting various substances in the blood. This statement is correct.

3. **Evaluate the Second Option: Globulin**:
- **Function**: Provide antibody-mediated immunity.
- **Analysis**: Globulins play a significant role in immune responses, including the production of antibodies. This statement is also correct.

4. **Evaluate the Third Option: Fibrinogen**:
- **Function**: Help in the coagulation of blood.
- **Analysis**: Fibrinogen is a crucial protein in the blood clotting process, converting to fibrin during coagulation. This statement is correct as well.

5. **Evaluate the Fourth Option: All of These**:
- Since all the previous options (Albumin, Globulin, and Fibrinogen) are correctly matched with their functions, the option that states "All of these" is also correct.

### Conclusion:
- All the statements regarding the blood plasma proteins and their functions are correct. Therefore, the correct answer is **Option 4: All of these**.
