Which of the following molecules has a three-fold axis of symmetry?

Given below are two statements:
Statement $(I) :$ For $ClF_3$,all three possible structures may be drawn as follows:
(Image provided)
Statement $(II) :$ Structure $III$ is most stable,as the orbitals having the lone pairs are axial,where the $\ell p-bp$ repulsion is minimum.
In the light of the above statements,choose the most appropriate answer from the options given below:

The number of lone pairs of electrons on the central atom of $ClF_3, NF_3, SF_4,$ and $XeF_4$ respectively are:
