Adaptive immune system : It is called as 'acquired immune system' and is sub system of the immune system which is composed of different specialized immune cells that fight the pathogens entering body and will protect body in many ways. In acquired immunity the antibodies are produced in the body by the 'stimulation' but not naturally. The Answer related discussion: Characters of adaptive immune system are 1.Improved response with repeated exposure to same pathogens . 2. Recognition of pathogen associated patterns 3. React slowly to the infectious agents on first infection. 4.can respond to specific molecules of specific pathogens ex: vaccine's. So answer is "All of the options apply no exception."
