D. V

Answer

To answer the question "Which clotting factor has been rejected now?", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Clotting Factors**: Clotting factors are proteins in the blood that help control bleeding. They work together in a complex cascade to form a blood clot.

2. **Identifying Clotting Factors**: The main clotting factors include Factor I (Fibrinogen), Factor II (Prothrombin), Factor III (Tissue factor), Factor IV (Calcium ions), Factor V (Proaccelerin), Factor VII (Proconvertin), Factor VIII (Anti-hemophilic factor), Factor IX (Christmas factor), Factor X (Stuart-Prower factor), Factor XI (Plasma thromboplastin antecedent), Factor XII (Hageman factor), and Factor XIII (Fibrin-stabilizing factor).

3. **Focusing on Factor VI**: In the context of the question, we need to focus on Factor VI. Historically, Factor VI was thought to be a distinct clotting factor, but it has since been rejected as a separate entity.

4. **Conclusion**: The clotting factor that has been rejected is **Factor VI**.

### Final Answer:
The clotting factor that has been rejected now is **Factor VI**.
