Endogenous antigens are associated with molecules in order to activate which of the following cells?

Endogenous antigens are associated with molecules in order to activate which of the following cells? Correct Answer Class I MHC

Endogenous antigens are associated with MHC class I molecules and play a very important role in activating cytotoxic CD8+ T cells. This activation leads to killing of infected cells as well as tumour cells. MHC class I molecules are very important as they are the base of immune recognition, its response and regulation in the body. These mechanisms can possibly take place only if MHC class I molecules bind to antigen peptides in order to from antigen peptide-MHC class I molecular complexes.
