The correct option is A Both A and R are true and R explains A
Adaptive or acquired immunity in humans is acquired through contact with specific pathogens during our lifetime. In the case of pathogen-specific diseases like chicken pox, the memory cells in the immune system record necessary information about the chickenpox virus in the initial or first attack. In the second invasion of the same pathogen, the immune system would be able to provide a specific, faster and intensified response. Such a response is called the secondary response.
