B) When the first chain of the antigen receptor is produced it combines with a surrogate chain.
C) Cells bearing self-reactive antigen receptors undergo apoptosis.
D) MHC molecules are required to facilitate progression through the developmental pathway.
E) T cells do not rearrange their antigen-receptor genes in the bone marrow.
