b. variolated immune system
c. antigenic immune system
d. adaptive immune system
mark for review (will be highlighted on the review page)

Explanation:

The innate immune system is the first line of defense and responds immediately to infection or injury. The variolated immune system is not a standard term for an immune system component. The antigenic immune system is not a recognized part of the immune system classification. The adaptive immune system responds later, developing specific responses over time. So the correct answer is the innate immune system.

Answer:

A. Innate immune system
