The correct option is B Lone pair and double bond occupy the axial position in trigonal bipyramidal structure.
According to Bent's Rule, the most electronegative element occupy the hybrid orbital having a less percentage s-character or we can say that the most electronegative element occupies the axial postion.
Large atoms, lone pairs and double bonds occupies equatorial positions in a trigonal bipyramidal structure to minimize repulsions.
Lone pair-lone pair repulsions are always higher than lone pair-bond pair repulsions and bond pair-bond pair repulsions .
