The correct Answer is:
To solve the question, we need to evaluate each statement regarding immunity and determine which ones are correct. ### Step-by-Step Solution: 1. **Evaluate Statement A**: - Statement: "Passive immunity is slow & takes time to give full effective response." - Explanation: Passive immunity involves the transfer of preformed antibodies to an individual. This means the body does not have to produce antibodies on its own, and the response is immediate. Therefore, this statement is incorrect. 2. **Evaluate Statement B**: - Statement: "In active immunity, readymade antibodies are directly given to protect the body against active infections." - Explanation: Active immunity occurs when the body produces its own antibodies in response to an antigen. Readymade antibodies are associated with passive immunity, not active immunity. Thus, this statement is also incorrect. 3. **Evaluate Statement C**: - Statement: "Passive artificial immunity is used for treatment of disease." - Explanation: Passive artificial immunity involves the administration of antibodies (e.g., antivenom for snake bites) to treat diseases. This statement is correct. 4. **Evaluate Statement D**: - Statement: "Active artificial immunity is the basis of vaccination." - Explanation: Active artificial immunity is indeed the basis of vaccination, where a person is exposed to a weakened or killed pathogen to stimulate an immune response. This statement is correct. ### Conclusion: - The correct statements are **C and D**. ### Final Answer: The correct statements are C and D. ---
