(D) An $H_2O$ molecule has two hydrogen atoms attached to an oxygen atom through covalent bonds.Each hydrogen atom can form one hydrogen bond with the lone pair of an oxygen atom of a neighboring $H_2O$ molecule.The oxygen atom has two lone pairs,each of which can accept a hydrogen bond from a hydrogen atom of a neighboring $H_2O$ molecule.Therefore,an $H_2O$ molecule can participate in a total of $4$ hydrogen bonds ($2$ as a donor and $2$ as an acceptor).

The maximum possible number of hydrogen bonds in which an $H_2O$ molecule can participate is
