Solution

Dear Student,

Vander Waal's force is the weakest force among all existing forces, resulting in intermolecular forces, the chemical molecule is comprised of electrons in motion so the electron concentration from region to region exhibits electropositive a weak force which gets attract to the another molecule by experiencing Vander Waal's force. The intermolecular force exhibits with the sum of attractive and repulsive forces among molecules.

Hence the answer is Option (C) cation and anion attractive forces.

Regards.
