Respuesta :
When activated become plasma cells and produce antibodies. Option B.
During T-cell-dependent activation B cells take up antigens and present a portion of it on their surface via the major histocompatibility complex. Helper T cells can recognize these antigens via MHC and activate B cells. T cells can clear out infected and cancer cells. It also regulates the immune response by helping B lymphocytes eliminate invading pathogens. B cells make antibodies.
Each B cell produces one type of antibody each with a unique antigen-binding site. When naive or memory B cells are activated by antigen they proliferate and differentiate into antibody-secreting effector cells. B-cells and T-cells are the white blood cells of the immune system that are responsible for the adaptive immune response of an organism. Both cells are made in the bone marrow. B cells mature in the bone marrow and T cells migrate to the thymus where they mature.
