Options

A. Subclevial vein
B. Pulmonary artery
C. Artery which enters in legs
D. Right ventricle

Answer

### Step-by-Step Solution:

1. **Understanding Lymph**: Lymph is a colorless fluid that is similar to blood plasma but does not contain red blood cells or platelets. It primarily consists of white blood cells (WBCs), particularly T cells and B cells.

2. **Function of Lymph**: The lymph plays a crucial role in filtering out microbes, organic wastes, and other unwanted materials from the tissues. It helps maintain fluid balance in the body and is part of the immune system.

3. **Transportation of Lymph**: Lymph is carried through lymphatic vessels. These vessels transport lymph away from the tissues and towards larger lymphatic ducts.

4. **Pathway of Lymph**: The lymph flows into the lymphatic ducts. From there, it moves into the right lymphatic duct, which is one of the largest lymph vessels in the body.

5. **Final Destination**: The lymph is ultimately drained into the right subclavian vein. This is where the lymph re-enters the bloodstream.

6. **Conclusion**: Therefore, the correct answer to the question "Lymph vessels pour their materials in" is the right subclavian vein.
