Please help! M/J 2012 paper 12 question 35 Link: http://www.smarteduhub.com/files/documents/9700_s12_qp_12.pdf
The graph shows the amount of antibody produced in response to an antigen. From the graph, which statement is correct? A It takes 25 days to achieve active immunity. B Memory cells for this antigen are present in the body within 20 days. C T-helper lymphocytes are activated on day 12. D The second exposure to the antigen occurred on day 25
How come the answer is B??
