In which of the following molecules all bond lengths are not equal?

In the compounds having ${\mathrm{sp}}^3 \mathrm{d}$ or ${\mathrm{sp}}^3{ \mathrm{d}}^2$ hybridisation, all bonds are not equal length.
In the case of ${\mathrm{PCl}}_5$ two axial, $\mathrm{P}-\mathrm{C}$ bonds are longer than the three equatorial bonds as they suffer greater repulsion than the equatorial bonds.

But for ${\mathrm{SF}}_6$ the equatorial bonds are longer than the axial one. So correct options are $\mathrm{A},\mathrm{B}$
