Vedclass · Answer

(A) Primary lymphoid organs are the sites where lymphocytes originate and/or mature and become antigen-sensitive. These include the bone marrow $(VI)$ and the thymus $(III)$.Secondary lymphoid organs provide the sites for interaction of lymphocytes with the antigen, which then proliferate to become effector cells. These include the spleen $(IV)$, lymph nodes $(V)$, tonsils $(VII)$, Peyer's patches of the small intestine $(II)$, and the appendix $(I)$.Therefore, $P = \{III, VI\}$ and $Q = \{I, II, IV, V, VII\}$.
