Which of the following molecular interactions include not only London dispersion forces but also dipole-dipole interaction?

Due to the absence of symmetry in PF₃, in addition to the London dispersion force, there are additional dipole-dipole interactions and only one pair of electrons in the P orbitals, which prevents the dipoles from cancelling each other out.

${\mathrm{AlF}}_3$ is ionic while ${\mathrm{BF}}_3$ and ${\mathrm{SiF}}_4$ are non-polar.
