Explanation

The correct answer is B because lymphocyte cells are a type of white blood cell produced in the bone marrow. Bone marrow is the soft, spongy tissue found inside the cavities of long bones such as the femur and humerus. It serves as the primary site for hematopoiesis, which is the process of creating all types of blood cells, including B lymphocytes and T lymphocytes. While T cells later migrate to the thymus to mature and lymphocytes are stored in organs like the spleen, their initial formation occurs in the bone marrow of long bones.
