Answer:
The correct answer will be option D-secondary lymphoid tissues.
Step-by-step explanation:
Follicular dendritic cells or FDCs are non-migratory dendrite cells found in the follicles of B cell areas of any secondary lymphoid organs and belong to the stromal cells of these lymphoid organs.
They help in providing immunity by shaping the responses of B in the chronic inflammatory response and auto-immune disease. These cell help in the selection of memory B cells by presenting antigens to potential memory cells to which only B cell with B cell receptors can bind.
Thus, option D-secondary lymphoid tissues is the correct answer.
