What types of cells are present in Hodgkin's lymphoma?

A. Reed-Sternberg cells are the hallmark malignant cells found in Hodgkin's lymphoma and are used to confirm the diagnosis. They are large, abnormal lymphocytes with a characteristic “owl’s eye” appearance seen on microscopic examination of lymph node tissue. B. Stem cells are immature precursor cells and are not specific to Hodgkin's lymphoma. C. RBCs are red blood cells and are not related to the pathophysiology of Hodgkin's lymphoma. D. Bence-Jones proteins are associated with multiple myeloma, not Hodgkin's lymphoma.
