(B) Innate immunity is non-specific type of defense that is present at the time of birth. It consists of four types of barriers:$1$. Physical barriers: e.g.,skin,mucus coating of the epithelium lining the respiratory,gastrointestinal,and urogenital tracts.$2$. Physiological barriers: e.g.,acid in the stomach,saliva in the mouth,and tears from eyes.$3$. Cellular barriers: e.g.,polymorpho-nuclear leukocytes ($PMNL$-neutrophils),monocytes,and natural killer cells in the blood.$4$. Cytokine barriers: e.g.,virus-infected cells secrete proteins called interferons which protect non-infected cells from further viral infection.Since all options (Physical,Chemical,Physiological,Cellular) are technically part of the innate immunity classification (where Chemical is often grouped under Physiological or Physical),the question implies a standard classification. However,based on $NCERT$,the four barriers are Physical,Physiological,Cellular,and Cytokine. 'Chemical' is not listed as a primary category in $NCERT$,making it the correct choice for '$NOT$ included'.

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