(C) hydrogen bond is formed when a hydrogen atom is covalently bonded to a highly electronegative atom (like $F, O, N$) and is attracted to another electronegative atom with a lone pair.In option $(A)$,the $H$ atom of $H_2O$ (which is more acidic) is attracted to the lone pair on the $N$ atom of $NH_3$. This is a correct representation.In option $(B)$,the $H$ atom of the $-OH$ group in $o$-chlorophenol forms an intramolecular hydrogen bond with the $Cl$ atom. While $Cl$ is not as electronegative as $F, O, N$,it can participate in weak hydrogen bonding in specific geometries.In option $(C)$,the $H$ atom of $NH_3$ is shown bonded to the $O$ atom of $H_2O$. Since $N$ is less electronegative than $O$,the $N-H$ bond is less polar than the $O-H$ bond. Therefore,the $H$ atom in $NH_3$ is less acidic and less capable of forming a strong hydrogen bond compared to the $H$ atom in $H_2O$. Thus,$(C)$ is the least favorable representation among the given choices.
