Which part of a lymph node contains follicles where lymphocytes reside?

Explanation:
The region containing follicles where lymphocytes reside is the cortex. The cortex lies just beneath the capsule and hosts lymphoid follicles, which are clusters mainly of B cells. Primary follicles are dormant clusters of B cells, while secondary follicles have germinal centers where B cells proliferate and differentiate during an immune response. The medulla contains medullary cords and sinuses with plasma cells and macrophages, the capsule is the outer protective layer, and the hilus is the entry/exit point for vessels. So the cortex is the site of these B-cell follicles.
