Which of the following is crucial to activation of the acquired immune response?
A) memory cells
B) presentation of MHC- antigen complex on a cell surface
C) phagocytosis of antibody- antigen complex by macrophages in the blood the humoral response)
D) somatic hypermutation

Presentation of MHC-antigen complex on a cell surface is critical to the activation of the acquired immune response as it allows recognition and activation of specific T cells, which can then activate B cells and effector T cells to respond to the antigen. Memory cells (A) are important for long-term immunity but are not necessary for initial activation of the immune response. Phagocytosis of antibody-antigen complexes (C) is a part of the humoral immune response but is not required for activation of the acquired immune response. Somatic hypermutation (D) occurs during the affinity maturation phase of the immune response and is not necessary for the initial activation.
