Vedclass · Answer

(D) Innate immunity is non-specific type of defense that is present at the time of birth. It provides different types of barriers to prevent the entry of foreign agents into our body. These barriers are categorized into four types: $1$. Physical barriers (e.g.,skin,mucus coating of the respiratory,gastrointestinal,and urogenital tracts). $2$. Physiological barriers (e.g.,acid in the stomach,saliva in the mouth,tears from eyes). $3$. Cellular barriers (e.g.,polymorpho-nuclear leukocytes,monocytes,and natural killer cells). $4$. Cytokine barriers (e.g.,interferon proteins which protect non-infected cells from further viral infection). Therefore,the correct answer is $D$ (Barriers).

List-$I$	List-$II$
$(a)$ $IgG$	$(i)$ Protection of body surfaces
$(b)$ $IgA$	$(ii)$ Regulation of allergic reactions
$(c)$ $IgM$	$(iii)$ Activates $B$-cells
$(d)$ $IgD$	$(iv)$ Protection of body fluids
$(e)$ $IgE$	$(v)$ Protection of blood circulation
