Answer 2

Non-specific defenses are defenses of the innate immune system. The first line of defense is the skin, mucous membranes, etc. Second line is fever among other things. Therefore, the answer is B. You can eliminate A and C because B cells and T cells are part of the adaptive immune system which mounts immune responses against specific pathogens.
