the bodys nonspecific defenses include
interferon.
skin.
all of these
complement.
inflammation.

Explanation:

Nonspecific defenses (innate immunity) of the body include physical barriers (like skin), chemical defenses (like complement), cellular responses (like inflammation), and antiviral proteins (like interferon). So interferon, skin, complement, and inflammation are all part of nonspecific defenses. Thus, "all of these" is correct.

Answer:

C. all of these (assuming the options are labeled A - E with "all of these" as one option; if the option with "all of these" is, for example, the third option as per the list, the answer is the option "all of these" among the choices, typically presented as the option with text "all of these" in the multiple - choice list)
