A:artificial active immunity
B:artificial passive immunity
C:natural active immunity
D:natural passive immunity

Help would really be appreciated🙂🙂

Active immunity is when the immune system is stimulated to produce antibodies and memory cells; passive immunity is when a recipient receives antibodies from an exogenous source. Either of these can be natural or artificial.
Artificial active immunity is induced by a vaccine; the vaccine is artificial, but it still stimulates the immune system to produce its own antibodies and memory cells.
Artificial passive immunity is when antibodies are obtained from an exogenous source (such as an antiserum, or antitoxin) and given to a recipient - this type of immunity is very short-lived.
Natural active immunity is caused by infection with a pathogen which stimulates the immune system to produce antibodies and memory cells.
Natural passive immunity is when maternal antibodies cross the placenta and enter the feotal circulation in utero. These antibodies (which are IgG antibodies) provide protection for a round 6-12 months after birth.
