Question

Quizplus · Accepted Answer

The secondary response to an antigen leads to a large increase in the production of IgG antibodies, usually by 100-fold to 1,000-fold, compared to the primary response. The lag time is also reduced for the secondary response. Therefore, option B is the correct statement. The other options are incorrect because, during the secondary response, IgM production is reduced, not increased to the extent of a 100-fold increase (option A and C) and the response time is reduced (option D).
