Match the type or cause of clonal expansion with the correct situation. Use each choice just one time and make the best match. Clonal expansion of B cells because the cells are infected with EBV Clonal expansion of B-cells because these B-cells have B Cell Receptors that recognize a non-self antigen Clonal expansion of T-cells that have a T Cell Receptor that recognizes EBV antigens A. normal adaptive response by the B cells B. part of pathogenesis of mono C. This allows the adaptive immune system to shut down active EBV infection
