Ans: A, C
Feedback:
Naturally acquired active immunity occurs when the person is exposed to and experiences a disease and the body manufactures antibodies to provide future immunity to the disease. This would be an individual who is exposed to chickenpox or pertussis for the first time and has no immunity to the disease. Artificially acquired active immunity occurs when an individual is given a killed or weakened antigen, which stimulates the formation of antibodies against the antigen. The antigen does not cause the disease, but the individual still manufactures specific antibodies against the disease. Administration of a vaccine to an individual who has no immunity would be an example of artificially acquired active immunity.
