The correct Answer is:
To answer the question, "Which provides micro-environment for the development and maturation of B-lymphocytes?", we can follow these steps: ### Step-by-Step Solution: 1. **Understanding B-lymphocytes**: B-lymphocytes, also known as B cells, are a type of white blood cell that plays a crucial role in the immune system, particularly in the adaptive immune response. 2. **Identifying the Site of Development**: B-lymphocytes originate from hematopoietic stem cells in the bone marrow. This is the primary site where they develop and mature. 3. **Role of Bone Marrow**: The bone marrow provides a specialized microenvironment that is essential for the development and maturation of B-lymphocytes. It contains various stromal cells and extracellular matrix components that support B cell differentiation. 4. **Other Potential Sites**: While the spleen and thymus are important for the immune system, they do not provide the primary microenvironment for the development of B-lymphocytes. The thymus is primarily involved in T-lymphocyte maturation. 5. **Conclusion**: Therefore, the correct answer to the question is that the **bone marrow** provides the microenvironment for the development and maturation of B-lymphocytes. ### Final Answer: **Bone marrow** provides the micro-environment for the development and maturation of B-lymphocytes. ---
