The correct statement(s) about intermolecular forces is(are)

The potential energy between two point charges approaches zero more rapidly than the potential energy between a point dipole and a point charge as the distance between them approaches infinity.

The average potential energy of two rotating polar molecules that are separated by a distance r has $1/r^3$ dependence.

The dipole-induced dipole average interaction energy is independent of temperature.

Nonpolar molecules attract one another even though neither has a permanent dipole moment.
