Which lymphocyte moves to the thymus gland to mature? A. B cells B. T cells C. NK cells D. None

Answer to the Question

The lymphocyte that moves to the thymus gland to mature is B. T cells.

Explanation

T cells, or T lymphocytes, originate from progenitor cells in the bone marrow and migrate to the thymus gland for maturation. In the thymus, T cells undergo a selection process to ensure they can respond appropriately to pathogens while being tolerant of the body's own tissues. This maturation is crucial for the development of a functional adaptive immune response. On the other hand, B cells mature in the bone marrow, and Natural Killer (NK) cells do not undergo maturation in the thymus. Therefore, the correct answer is T cells.
