A. Bone marrow
B. Spleen
C. Lymph node
D. Thymus
E. Tonsil
ANS: D. Generative lymphoid organs are the organs where lymphocytes first express antigen receptors and attain functional maturity. Although T cell precursors arise in the bone marrow, these precursors migrate to the thymus, where maturation takes place. In contrast, B cells mature in the bone marrow. Spleen, lymph node, and tonsil are secondary lymphoid organs populated by mature B and T cells.
