In general, which is the strongest type of intermolecular force and responsible for the very high melting points of solid salts?

I think that it's hydrogen bonding, but during class discussion it was stated that it's ionic interactions. Will you please explain to me why it is ionic interaction. The question asks about intermolecular force, which is the force between molecules. Ionic interaction is bonding inside the molecule between ions.

Please help to understand.
Thank you

Take a look at NaCl crystal structure - can you separate intermolecular and intramolecular interactions?

Thank you, I did not see the big picture
