Answer: option B) proton-electron.
The particles inside a salt crystal are ions. The electrostatic attraction between the positive ions are the negative ions is responsible for the crystal structure. In last stay, the protons are responsible for the positive charge and the electrons for the negative charge. Then you can say that the interaction proton-electron is responsible for the force of attraction between the particles in a salt crystal.
Atoms are made up of Protons and neutrons in the nucleus, and then rings of electrons on the outer shells! so in short, protons, neutrons and electrons. :)
The answer is london dispersion forces. It is one of two intermolecular forces that is present in all molecules!
