The thymus plays a crucial role in T cell development, it does not produce B cells, thus option A is incorrect. The spleen does not produce B cells either and does not work specifically with lymph nodes in humoral immunity, thus option B is incorrect. Lymph nodes do not secrete lymphatic fluid, they filter lymph to remove pathogens and help activate immune cells, but the spleen also filters the blood to remove pathogens, thus option C is incorrect. The correct statements are D and E, as both the lymph nodes and spleen are involved in filtering pathogens from the lymph and blood, and the thymus is the site of T cell development.
