Answer 3

Im to tierd to properly understand the question so i'll explain what memory cells are.
Main immunological memorycells are B-memorycells (deriving from B-plasma cells) & T-memorycells (Deriving from CD8 (Cytotoxic T cells.))
When a pathogen has been succefully fought off, these memory cells with the antigen of that perticular pathogen is stored. In the scenario where the body encounters the same pathogen again, it begins a immediate immunological response and massproduce to counter the Memorycells Antigen which has been recongnized.
B-plasmacells produce 3 000 000antibodies/per cell/per second.
And Cytotoxic T cells targets the pathogen.
