Kingdoms are Archaebacteria, Eubacteria, Protista, Fungi, Plantae, and Animalia.
I'm not sure if these 6 kingdoms I listed are one of the"which of the following"options you asked for so I hope it helps.
The answer for the first question is B. mucus sweat and tears, all of those are defenses that the body uses when attacked. Now for the second option is A the answer because the first filter that a virus or a desease must pass is indeed the skin. Hope is good for you
