C) Metals typically have very high melting points due to the strength of the metallic bond. Covalent compounds usually lack strong forces between molecules, and nonmetallic solids are too broad a category to quantify in this way. Intermolecular forces can be significant in ionic compounds, but not as strong as the metallic bond.

I'd go with c. Metal conduct heat very well, and as a result, tend to have higher melting points because they can dissipate the heat to their neighboring atoms within the crystal lattice.
The element with the highest melting point is tungsten (a metal), at 6192 °F That's hot!!

I just googled it, and it seems tantalum hafnium carbide is the highest. It says it is a "refractory compound" which implies a metal to me (but I could be wrong). Also, Tungsten, a metal, has a very high (around 3400C) melting point.
