Which of the following statements about MHC proteins is correct?
A CD8 expressing $T$ cell is usually activated by the presentation of a peptide in association with MHC II proteins.
MHC II proteins are expressed on the cell surface of all of the cells in the body.
The loading of the peptide occurs in an intracellular compartment for both $\mathrm{MHC}$ I and $\mathrm{MHC}$ II proteins even though the peptides are derived from endogenous and exogenous antigens respectively.
$\mathrm{MHC}$ I proteins bind peptides that are at least 15 amino acids in length and MHC II proteins bind peptides that are about $8-10$ amino acids in length
MHC gene products on the surface of antigen presenting cells function as both antigen receptor and $T$ cell receptors.
