Why is the secondary immune response to a pathogen faster than the primary response?
Answer and explanation
Correct answer: C. Memory cells quickly divide into plasma cells that produce antibodies

Answer: Memory cells quickly divide into plasma cells that produce antibodies. Why not the others: antibody levels fall after infection; macrophages do not prevent all infection; phagocytes do not make antibodies.
