Solution

The correct option is A Artificial acquired active immunity
The composition of vaccines is dead or live but attenuated pathogens, toxoids or toxins released by the pathogens. The immunity acquired artificially by vaccination through the injection of attenuated pathogens is called artificially acquired active immunity. These vaccines stimulate the production of antibodies by the immune system that is capable of protecting the person from a disease. Thus the correct answer is option A.
