The spleen and lymph nodes both have a hilum, which is a concave area where blood vessels and nerves enter and exit the structure. The other options (A, B and D) do not have a well-defined hilum. Tonsils and appendix are not encapsulated structures, whereas thymus and aggregated lymphoid nodules lack a well-defined hilum. MALT (mucosa-associated lymphoid tissue) is widely distributed throughout mucosal linings of various organs and does not have a distinct anatomical structure.
