The correct answer is dipole-dipole interactions and London dispersion forces (induced dipole-dipole forces).
Dipole-dipole interaction is attractive force which occurs between the positive end of one polar molecule and the negative end of another polar molecule.
London force is temporary force and it is the weakest intermolecular force. It is an attractive force that occurs when the electrons (e-) in two adjacent molecules occupy positions that make the atoms form temporary dipoles.
