What occurs during the antigen detection stage of the antibody-mediated immune response initiated by T cell activation?

A) Cytotoxic T cells destroy body cells that are infected with a pathogen.
B) Helper T cells activate an antigen-specific B cell to divide and secrete antibodies.
C) A T cell displaying an antigen-specific T cell receptor (TCR) binds to the antigen on the surface of an antigen presenting cell.
D) Helper T cells are activated by the TCR.
E) A B cell degrades the pathogen and produces antigens.
