Answer :
B) Clonal selection activates specific lymphocytes upon recognizing antigens, leading to clonal expansion and the creation of immune memory cells.
During clonal selection, only those lymphocytes whose receptors match the specific antigens of the pathogen will be activated and allowed to proliferate. These activated lymphocytes make numerous identical copies of themselves, creating a large population of cells ready to combat the infection effectively. This ensures that the immune system can mount a strong and targeted response to specific pathogens.
