Solution:
Active immunity means pathogen or antigen when introduced in the body triggers formation of antibodies. Passive immunity means directly antibodies are injected. It can be natural or artificial. Colostrum is the first milk produced by the mother after parturition. It is a rich of IgA and thus through this milk the antibodies are directly delivered to the baby. Thus, this is an example of passive immunity.
