After 12 months of treatment scans confirmed that she was in remission and there was no evidence of abnormal lymphocytes. However, six months later at a follow up appointment the patient complained of bone pain in her hips and sternum and her oncologist noticed swollen lymph nodes and ordered a biopsy, CBC, and PET scan. The blood tests identified an abnormally high number of circulating antibodies in the blood and a high blood viscosity (thickness) as a result. The results of the remaining tests confirmed this and resulted in a diagnosis of chronic lymphocytic leukemia, a blood cancer that results in slow progressing excess lymphocyte proliferation. This is a rare but not uncommon side effect of the drugs meant to treat the lymphoma. The doctor ordered plasmapheresis to treat the high blood viscosity and decided to begin her on a course of treatment involving brentuximab, a monoclonal antibody therapy.      Name and describe three ways that circulating antibodies target foreign invaders for elimination.

Based on this information, what line of cells give rise to RSCs and why did you choose that answer?
