a. Lymphokine-producing cells
b. T-cytotoxic cells
c. Helper T cells
d. Macrophages
ANS: B
Cell-mediated immunity is driven by T-cytotoxic (Tc) cells that attack antigens directly and de-stroy cells that bear foreign antigens. Lymphokine-producing cells, helper T cells, and macro-phages do not attack antigens directly and destroy cells that bear foreign antigens.
