Solution

The correct option is A True
True. Passive immunity can occur naturally when maternal antibodies are transferred to the fetus through the placenta. It can also be induced artificially when high levels of antibodies specific to a pathogen or toxin are transferred to non-immune persons (examples: immunoglobulin therapy or antiserum therapy).
