(D) In $SF_4$,the central atom is sulfur $(S)$.Sulfur has $6$ valence electrons.It forms $4$ single bonds with $4$ fluorine atoms,using $4$ valence electrons.This leaves $6 - 4 = 2$ electrons,which form $1$ lone pair on the sulfur atom.Thus,there are $4$ bond pairs and $1$ lone pair.The steric number is $4 + 1 = 5$,which corresponds to $sp^3d$ hybridization.Due to the presence of $1$ lone pair in the equatorial position of a trigonal bipyramidal geometry,the shape of the $SF_4$ molecule is see-saw.

The number of bond pairs,lone pairs present on the central atom of $SF_4$ molecule and its shape respectively are
