Final answer:
Red blood cells are derived from hematopoietic stem cells, specifically from the myeloid stem cell lineage known as Common Myeloid Progenitors (CMP).
Step-by-step explanation:
Red blood cells (RBCs) are derived from hematopoietic stem cells. During the process of hematopoiesis, which occurs in the bone marrow, two primary classes of stem cells form: myeloid and lymphoid stem cells. RBCs, or erythrocytes, emerge specifically from myeloid stem cells. These myeloid stem cells also give rise to other formed elements such as megakaryocytes (which produce platelets) and various types of leukocytes like neutrophils, eosinophils, and basophils. Lymphoid stem cells, on the other hand, develop into lymphocytes, including T cells, B cells, and natural killer (NK) cells, and are involved in the adaptive immune system.
Therefore, from the options provided, RBCs are derived from Common Myeloid Progenitors (CMP), which are a type of myeloid stem cell. Option (2) 'CMP' is the correct choice in this context.
