Which blood protein play a major role in osmotic balance ?

Options

A. Albumin
B. Globulin
C. Fibrinogen
D. All of these

Answer

To solve the question "Which blood protein plays a major role in osmotic balance?", we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question is asking which specific blood protein is primarily responsible for maintaining osmotic balance in the body.

2. **Identify the Options**: The options given are:
- Albumin
- Globulin
- Fibrinogen
- All of the above

3. **Evaluate Each Option**:
- **Albumin**: This protein is known to play a crucial role in maintaining osmotic pressure in the blood. It helps to keep fluid in the bloodstream and prevents it from leaking into other tissues.
- **Globulin**: This protein is primarily involved in immune responses and blood clotting, rather than osmotic balance.
- **Fibrinogen**: This protein is essential for blood clotting and does not play a significant role in osmotic balance.
- **All of the above**: Since not all the proteins listed contribute to osmotic balance, this option is incorrect.

4. **Conclusion**: Based on the evaluation, the protein that plays a major role in osmotic balance is **Albumin**.

### Final Answer:
The blood protein that plays a major role in osmotic balance is **Albumin**.
