Why is part d polar? Do lone pairs cause dipole moments?

The lone pair causes the S-F bonds to not be directly symmetrical from one another and therefore their dipole moments don’t cancel out.

Lone pairs cause molecules to be polar because they have a strong negative presence and are usually not cancelled out by a symmetric pull in the other direction.
