The correct Answer is:
To solve the question regarding the two statements about active immunity and snake antivenom, we can analyze each statement step by step. ### Step 1: Analyze Statement 1 - **Statement 1**: "Active immunity is developed when a person's own cells produce antibodies in response to infection or vaccine." - **Explanation**: Active immunity occurs when the immune system is stimulated to produce its own antibodies in response to an antigen, which can be from an infection or a vaccine. This process takes time as the body needs to recognize the antigen and mount a response, but it results in long-lasting immunity. ### Step 2: Analyze Statement 2 - **Statement 2**: "Injection of snake antivenom against snake bite is an example of active immunization." - **Explanation**: Snake antivenom contains preformed antibodies that are injected into a person who has been bitten by a snake. This is not an example of active immunization; rather, it is an example of passive immunity. In passive immunity, the antibodies are provided from an external source, and the body does not produce its own antibodies in response to the antigen. ### Step 3: Conclusion - **Correctness of Statements**: - Statement 1 is correct because it accurately describes active immunity. - Statement 2 is incorrect because it describes passive immunity, not active immunization. ### Final Answer The correct option is that Statement 1 is true, and Statement 2 is false. ---
