Which are examples of non-specific defenses?
mucus, stomach acid, and t cells
skin, digestive enzymes, and fever
lysozyme, phagocytes, and b cells

Option). skin, digestive enzymes, and fever.

Explanation:

Non-specific defense is a type of immune defense, which provides response against many antigens and is not specific for a particular pathogen. Skin, mucus, lysozymes, digestive enzymes, and inflammation are components of non-specific defense.

Skin provides protection against all external pathogens as it inhibits the entry of pathogens to the body. Digestive enzymes kill bacteria or other pathogens present in food during digestion. Fever shows an inflammatory response of body, which kills pathogens due to increased body temperature as many pathogens cannot survive at high temperature.

On the other hand, T cells and B cells are components of specific immune defense that act against particular type of antigens.

Thus, the correct answer is option). skin, digestive enzymes, and fever.
