Answer
Both A and R are True.
Reason — Active immunity involves the body’s own immune system producing antibodies in response to an infection or vaccine. It provides long-lasting protection. Immunogens (like parts of bacteria or viruses) stimulate the immune system to produce a response. This can happen through natural infection or vaccination.
