Answer:
T helper (CD4+): MHC I
Explanation:
T helper (CD4+) should be matched with MHC Class II while MHC Class I should be matched with T cytotoxic (CD 8+) cells. This is because T helper cells coreceptors recognize antigen presented on MHC II, to become an effector cell, while CD8+ recognize antigen presented by MHC I.
