False statement:
27. d. T-cells change into plasma cells and produce antibodies when stimulated.
Armed helper T cells stimulate the proliferation and then the differentiation of antigen-binding B cells. After several rounds of proliferation, B cells can further differentiate into antibody-secreting plasma cells.
