Ellen Villarreal · Answer 1

B) Saliva contains enzymes that destroy bacteria and prevent infection

Explanation:

Option A and B both are non specific immune response that means innate immune response. Innate immune response is always broad sense non specific immune response which can be external or internal. External response includes physical barriers like impervious skin, mucous membrane etc. While, internal non specific immune response includes chemical barriers like saliva, tears, pH of stomach etc.

Since as per this question they are talking about non specific internal response to harmful bacteria so option B will be the most appropriate choice.
