Answer:
The correct answer is- artificially acquired active immunity
Step-by-step explanation:
Naturally acquired active immunity generates in the body when an antigen comes in the body naturally and our immune system makes antibodies against that antigen to provide immunity to the body against that antigen.
In artificial acquired active immunity antigen is artificially induced in the form of vaccine against which our immune system makes antibodies. Vaccination mainly contains a disarmed pathogen that cannot cause disease but can excite an immune response to form memory against that antigen.
Therefore if the same antigen comes again in the body then the body will generate an exaggerated and quick immune response against that pathogen. Therefore the right answer is-artificially acquired active immunity.
