Answer

**Step-by-Step Solution:**

1. **Understanding T-cell Origin**: T-cells originate from hematopoietic stem cells, which are located in the bone marrow. This is the first step in their development.

2. **Location of Maturation**: Although T-cells start their development in the bone marrow, they do not mature there. The maturation of T-cells occurs in a specific organ.

3. **Identifying the Correct Organ**: The organ responsible for the maturation of T-cells is the thymus. This is crucial because the thymus provides the necessary environment and signals for T-cells to mature and become functional.

4. **Significance of the Thymus**: The term "T-cell" itself is derived from "thymus-dependent," indicating that their development and maturation are dependent on the thymus.

5. **Conclusion**: Therefore, the correct answer to the question "T-cells mature in:" is the thymus.

**Final Answer**: T-cells mature in the thymus.
