When a B cell is shown an antigen on a class II major histocompatibility complex (MHC) protein, it will go through , and B cells subsequently can become and/or __.

a) Activation, Proliferation, Memory cells, Plasma cells
b) Recognition, Differentiation, Helper cells, Killer cells
c) Apoptosis, Inhibition, T cells, B cells
d) Antigen binding, Clonal expansion, Macrophages, Antibodies

The B cell undergoes activation and proliferation when presented with an antigen on MHC II, resulting in the differentiation into memory cells and plasma cells to mount an immune response.

Explanation:

When a B cell is shown an antigen on a class II major histocompatibility complex (MHC) protein, it will go through activation, proliferation, and B cells subsequently can become memory cells and/or plasma cells. The correct answer to the student's question is a) Activation, Proliferation, Memory cells, Plasma cells.

To elaborate, upon the recognition of the antigen, B cells process and present the antigen using their MHC II molecules. Helper T cells recognize the presented antigen on the B cell's MHC II molecules. This interaction leads to the activation and proliferation of B cells. Following this, they differentiate into memory B cells, which serve to provide a rapid response upon subsequent exposure to the same antigen, or plasma cells, which are dedicated to producing and secreting antibodies that target the specific antigen.
