Answer» The CORRECT OPTION is (b) Clonal selection For explanation I WOULD say: Formation of a large number of effector cells against a particular antigen is called Clonal selection. It INVOLVES the formation of a clone of cells by each activated T-lymphocyte and antibody-producing plasma cells by activated B-lymphocyte, each exhibiting the specificity for the same antigen.
