The Difference Between T Cell Activation by Normal Antigens and T

The difference between T cell activation by normal antigens and T cell activation by superantigens is that superantigens

A) are not processed and presented by APCs and cause nonspecific activation of many T cells at once, including those that would not normally recognize the antigen.
B) cause nonspecific activation of many T cells at once, including those that would not normally recognize the antigen and suppress cytokine release.
C) suppress cytokine release.
D) cause nonspecific activation of many T cells at once, including those that would not normally recognize the antigen.
E) are not processed and presented by APCs.
