The answer is D. The response reaches maximum after 4 days.

This is a booster shot which elicits a response characterized by a rapid increase in IgG but not IgM antibody. In contrast, a primary response would initiate with IgM antibody and then peak with IgM and IgG antibody after 8-10 days. smiling face
