Answer

Correct option: A.
Active immunity
Active immunity, which is naturally acquired, occurs when the person is exposed to a live pathogen, develops the disease and becomes immune, as a result of the primary immune response. Artificially acquired active immunity can be induced by a vaccine.
Artificially acquired passive immunity is a short$-$term immunization by the injection of antibodies. Naturally acquired passive immunity occurs during pregnancy in which certain antibodies are passed from the maternal to the fetal bloodstream.
