Which of the following matches correctly?

Options

A. Factor - II : Thromboplastin
B. Factor -IV: Prothrombin
C. Factor - VIII: Antihaemophilic globulin
D. Factor XII : Haemophilic

Answer

To determine which of the following matches correctly, we will analyze each option provided in the question regarding blood clotting factors and their corresponding roles or names.

### Step-by-Step Solution:

1. **Identify Factor 2**:
- Factor 2 is known as Prothrombin. It is a precursor to thrombin, which is essential for the coagulation process.
- **Match**: Factor 2 is NOT matched with Thromboplastin (this is incorrect).

2. **Identify Factor 4**:
- Factor 4 refers to Calcium ions (Ca²⁺). Calcium ions are crucial for various steps in the coagulation cascade.
- **Match**: Factor 4 is NOT matched with Prothrombin (this is incorrect).

3. **Identify Factor VIII**:
- Factor VIII is also known as Anti-Hemophilic Globulin. It plays a significant role in the intrinsic pathway of blood coagulation and is essential for the activation of Factor X.
- **Match**: Factor VIII is correctly matched with Anti-Hemophilic Globulin (this is correct).

4. **Identify Factor 11**:
- Factor 11 is known as the Hageman factor. It is involved in the intrinsic pathway of coagulation.
- **Match**: Factor 11 is NOT matched with any incorrect pairing in the question, but it is not the focus of the correct answer.

### Conclusion:
The only correct match from the options provided is Factor VIII with Anti-Hemophilic Globulin.

### Final Answer:
The correct match is **Factor VIII - Anti-Hemophilic Globulin**.
