(B) Mucous

(C) Saliva

(D) Antibody

Ans: Antibody

Solution:

Antibody is NOT a part of the human nonspecific defense system.

The adaptive immune system is characterized by its ability to recognize and remember specific pathogens, leading to a more targeted and efficient response upon subsequent encounters.
