All of these choices are correct. Once cytotoxic T cells are produced, they bind to viral antigens that are processed by the MHC class I mechanism and presented on the surface of infected cells. Most nucleated cells process antigens through the MHC class I mechanism. When cytotoxic T cells bind to MHC class I processed antigens, they release lymphokines that activate other immune cells and ultimately destroy the infected cell.
