Explanation
Answer: C - The transfer of IgG from the mother’s bloodstream through the placenta and to the fetus is an example of passive natural immunity. Passive immunity is an immunity that does not produce antibodies as the result of the presence of an antigen. Natural immunity is an immunity that is not given artificially as is the case with immunizations. Natural immunity occurs after a person actually has had the infection.
