My educated (?) guess would be D.

Explanation:

Ionic compounds are non-molecular and tend to possess high melting points, and very high boiling points. Refer to the melting point of say NaCl, at 801 C.

On the other hand, molecular species are composed of discrete molecules, and the interparticle, i.e intermolecular, interactions tend to be much less in magnitude than those observed for non-molecular species. A, B, and C are contraindicated.
