Answer

Correct option: A.
Develops resistance against the attack of a disease.
Vaccination is a technique to develop immunity in individuals without infection. In vaccination, a preparation of antigenic protein of pathogens or weakened or dead pathogens is injected into a person who is required to be immune. The pathogens, given in a vaccine are unable to cause disease but are sufficient to generate the primary immune response. So, the correct answer is 'Develops resistance against the attack of a disease.'
