A plasma cell produces IgM molecules that recognize an antigenic determinant on an influenza virus. After several days, the cell begins to produce IgG molecules that recognize the same antigenic determinant. This process is called

The process described is class switching, which occurs when a B cell undergoes a process called somatic hypermutation, resulting in a change in the class of immunoglobulin produced from IgM to IgG, IgE, or IgA. This process allows a more efficient immune response to be mounted against a specific antigen. Activation, RNA splicing, gene mutation, and autoimmunity are not the correct terms to describe the process.
