Read the passage and answer the question given below.
Exposure of a host to antigens, whether from living or deceased microbes or other proteins, triggers the production of antibodies within the host's body, resulting in what is known as active immunity. Active immunity operates gradually, requiring time to reach its full effectiveness. Introducing microbes deliberately through immunization or through natural infection allows for the induction of active immunity. Conversely, when antibodies are administered directly to shield the body against foreign agents, it constitutes passive immunity. Colostrum, produced by the mother during the initial stages of lactation, offers passive immunity due to its richness in antibodies.
