Answer:

The correct answer is bone marrow and thymus

Lymphocytes are also complete the early phases of maturation in the primary lymphatic organs in the body. In humans, B cells are generated and mature in the bone marrow. However, T cells are produced in the bone marrow and maturation takes place in the thymus.
