The Adaptive Immune Response Differs from the Innate Response in That

The adaptive immune response differs from the innate response in that

A) memory.
B) B and T lymphocytes can each target multiple proteins, whereas the innate response targets only a single type of antigen.
C) the adaptive immune response involves physical barriers and nonspecific processes, whereas the innate immune response relies on the actions of B and T lymphocytes.
D) the innate immune response targets a specific immunogen and remembers it to mount an even stronger response on subsequent encounters with that immunogen, whereas the adaptive response is nonspecific and has no memory.
