Final answer:
Pluripotent hematopoietic stem cells differentiate into red blood cells, platelets, and various forms of white blood cells like lymphocytes and granular leukocytes. The correct answer is option A.
Step-by-step explanation:
The three possible branches of a pluripotent hematopoietic stem cell are red blood cells, platelets, and white blood cells. These stem cells can differentiate into multiple cell types that contribute to the blood and immune systems. Specifically, within the white blood cell category, hematopoietic stem cells can give rise to lymphoid stem cells and myeloid stem cells. Lymphoid stem cells develop into lymphocytes, including T cells, B cells, and natural killer (NK) cells, while myeloid stem cells differentiate into erythrocytes (red blood cells), megakaryocytes (which produce platelets), monocytes, and granular leukocytes such as neutrophils, eosinophils, and basophils.
