The attractive force that would result in the lowest melting point is C. Van der Waals forces.

Here's why:

A. Hydrogen-bonding forces are relatively strong intermolecular forces, stronger than Van der Waals and dipole-dipole interactions. Therefore, substances with hydrogen bonding usually have higher melting points.

B. Ionic electrostatic attractions are the strongest among the given options. They occur between ions in ionic compounds, and these compounds usually have high melting points due to the strong attractions between the positive and negative ions.

C. Van der Waals forces are the weakest intermolecular forces. They are temporary dipole interactions that occur between all molecules, whether polar or nonpolar. Substances with only Van der Waals forces usually have low melting points.

D. Dipole-dipole attractions are stronger than Van der Waals forces but weaker than hydrogen bonding and ionic attractions. They occur between polar molecules. Substances with dipole-dipole attractions have higher melting points than those with only Van der Waals forces but lower than those with hydrogen bonding or ionic attractions.
