Which of the following best describes an example of a nonspecific external response to harmful bacteria?

A) Phagocytes engulf and destroy invading bacteria.

B) Histamine causes areas invaded by bacteria to swell.

C) Antibodies recognize bacteria and attack them.

D) Enzymes in saliva break down bacterial cell walls.

I believe it is D, but I'm really not sure. This is part of a pretest, so dont nag me about that. Thx! :)
