Final answer:
The false statement about T cells is that they are primarily involved in humoral immunity, when they are in fact central to cell-mediated immunity.
Step-by-step explanation:
False Statement About T Cells
The false statement about T cells is c. This statement is incorrect because T cells are chiefly involved in cell - mediated immunity, not humoral immunity. Humoral immunity involves B cells and the production of antibodies that act in the body's fluids or 'humor'. T cells, especially cytotoxic T cells, play a critical role in directly attacking infected cells, employing mechanisms such as secreting perforins to destroy those cells. Both B cells and T cells originate in the bone marrow, but T cells mature in the thymus, which is why they are named as such.
