. Immunity created by B-cells is called—


(a)        Antibody mediated immunity          

(b)       Humoral immunity

(c)        Cell mediated immunity       

(d)       Both (a) and (b)

Best Answer

(d)       The plasma B cells are antibody factories. The antibodies pass into and circulate in the lymph to dispose of the antigens. For this, the antibodies selectively bind to the antigens, forming antigen-antibody complexes to destroy the antigens. Each person can make 107 to 108 different kinds of antibody molecules so that there is an antibody on a B cell to fit any antigen. Thus, there are numerous types of antigen-specific B-lymphocytes in the body. B-cells created mediated immunity and humoral  immunity also.
