During which stage of the immune response does the circulating lymphocyte containing the antigenic message return to the nearest lymph node?

During which stage of the immune response does the circulating lymphocyte containing the antigenic message return to the nearest lymph node?
a) Proliferation
Once in the node, the sensitized lymphocyte stimulates some of the resident dormant T and B lymphocytes to enlarge, divide, and proliferate.
b) Recognition
In the recognition stage, the immune system distinguishes an invader as foreign, or non-self.
c) Response
In the response stage, the changed lymphocytes function either in a humoral or cellular fashion.
d) Effector
In the effector stage, either the antibody of the humoral response or the cytotoxic T cell of the cellular response reaches and couples with the antigen on the surface of the foreign invader.
