Question

In an experimental situation, a virus is injected into a rabbit and the rabbit is allowed to make antibodies for the viral antigen. These antibodies are then removed from the rabbit plasma and injected into a human to help deal with the same viral disease. This would be an example ofa) Autoimmunity.b) Active immunization.c) Natural immunity.d) Innate immunity.e) Passive immunization.

Answer 1

The correct answer is e) Passive immunization

Step-by-step explanation:

In passive immunity, the antibodies against any pathogen or antigen are introduced in an organism's body from outside to provide it instant protection against that pathogen. The passive immunity can be natural or artificial.

Mother feeding antibodies rich milk to her child is an example of naturally acquired immunity and antibodies that are raised by humans in animals against an antigen when injected to a person shows an example of artificially acquired passive immunity.

So here human is given antibodies against a virus from outside which is raised in rabbit so it is an example of passive immunity which is artificially acquired.
