Match column I (molecule, E = lone pair electron ) with column II (possible repulsions for its stable structure)

	Column -I		Column -II
A)	${\mathrm{XY}}_4\mathrm{E}$	I	${90}^0$lone pair  - bond  pair repulsions = 6 when lone pair occupies equatorial positions
B)	${\mathrm{XY}}_3{\mathrm{E}}_2$	II	${90}^0$lone pair  - bond  pair repulsions = 4 when lone pair occupies equatorial positions
C)	${\mathrm{XY}}_2{\mathrm{E}}_3$	III	${90}^0$lone pair  - bond pair repulsions = 2 when lone pair occupies equatorial positions
		IV	${90}^0$lone pair  - bond pair repulsions = 3 when lone pair occupies equatorial positions
