(D) In the solid state,ionic substances exist as a lattice of ions.$PBr_5$ exists as an ionic solid composed of $[PBr_4]^+$ and $[Br]^-$ ions.$N_2O_5$ exists as an ionic solid composed of $[NO_2]^+$ and $[NO_3]^-$ ions.$Na_2SO_4$ is a typical ionic salt consisting of $[Na]^+$ and $[SO_4]^{2-}$ ions.$H_2O$ in the solid state (ice) exists as a molecular solid held together by hydrogen bonding,not as an ionic substance.Therefore,the correct answer is $H_2O$.
