By the end of which developmental stage does lymphoid tissue reach adult size?

Explanation:
Lymphoid tissue reaches adult size by the end of adolescence. The lymphoid system grows rapidly in childhood to support immune defense, with the thymus expanding through early childhood and peaking around puberty before gradually involuting. By late adolescence, the overall amount and arrangement of lymphoid tissue resemble adult proportions, even though the thymus may continue to shrink a bit with age. After adolescence, the remaining lymphoid tissues stay proportionate to adult size, marking the completion of growth in lymphoid tissue.
