"The only b..." is correct.
all are polar except PCl3 because of its distorted tetrahedral or pyramidal structure.
The distorted structure is due to lp-bp repulsion according to VSEPR. which does not allow the dipole moments to get cancelled.

All are correct, except for PCl3. PCl3 is polar because there is a lone pair of electrons on the phosphorus which makes the geometry pyramidal and does not allow for cancellation of the individual dipole moments.

only b is wrong. If you have problems identifying polar and nonpolar, check out he site below, it explains it in very simple terms.

Are you in a mood where you want to play professor or do you have a serious motive? To what use are you going to put the answers? In other words, in what context is the question?
