Vedclass · Answer

(B) Interferons are proteins secreted by virus-infected cells which protect non-infected cells from further viral infection.These proteins act as a chemical messenger system that triggers the antiviral state in neighboring cells.In the context of innate immunity,barriers are classified as: $1$. Physical barriers (e.g.,skin,mucus coating).$2$. Physiological barriers (e.g.,acid in the stomach,saliva in the mouth,tears from eyes).$3$. Cellular barriers (e.g.,leukocytes like $PMNL$-neutrophils,monocytes,and natural killer cells).$4$. Cytokine barriers (e.g.,interferons).Therefore,interferons are categorized under cytokine barriers.

Column-$I$	Column-$II$
$(a)$ Physical barrier	$(w)$ Saliva
$(b)$ Physiological barrier	$(x)$ Interferons
$(c)$ Cellular barrier	$(y)$ Skin
$(d)$ Cytokine barrier	$(z)$ Monocytes
