Identify the option in which the molecules are arranged in the correct order of their dipole moments

${\mathrm{BF}}_3<{\mathrm{NF}}_3<{\mathrm{NH}}_3$

In the case of NF₃, fluorine is more electronegative than nitrogen, so it will attract the shared pair of electrons towards itself. As a result, the resultant dipole moment decreases, whereas in ammonia, N is more electronegative than H, thus its resultant dipole moment is high.

BF₃ has zero dipole moment.
