Which statement about the specific immune response is FALSE? Each T or B cell has antigen receptors for only one specific antigen.

T and B cells recognize antigens by using antibodies bound to their surface membranes.

Unique antigen receptors are created by genetic recombination.

Antigens must be presented by an MHC molecule for T and B cells to recognize them.

All cells express MHC-I molecules, but only antigen-presenting cells express MHC-II molecules.
