The correct Answer is:
To determine which statements (A-D) are correct regarding immunization, let's analyze each statement step by step. ### Step-by-Step Solution: 1. **Statement A: "In immunization, a preparation of antigenic protein is induced in the body."** - This statement is **correct**. Immunization involves introducing an antigen (which can be a protein from a pathogen) into the body to stimulate an immune response. This helps the body recognize and fight the pathogen in the future. 2. **Statement B: "If a person is infected with a deadly microbe we need to directly inject vaccine."** - This statement is **incorrect**. If a person is already infected with a deadly microbe, they may require immediate treatment, such as passive immunization (e.g., antibodies) rather than vaccination, which is preventive and typically used before infection. 3. **Statement C: "Vaccine generate B & T memory cell."** - This statement is **correct**. Vaccines stimulate the immune system to produce memory B and T cells, which provide long-lasting immunity by remembering the pathogen for future encounters. 4. **Statement D: "Snake anti-venom is an example of active immunization."** - This statement is **incorrect**. Snake anti-venom is an example of passive immunization because it involves the injection of pre-formed antibodies to neutralize the venom, rather than stimulating the body to produce its own antibodies. ### Conclusion: The correct statements are A and C. Therefore, the option that includes all the correct ones only is A and C.
