Answer

C

Explanation

(A) `[CrF_(6)]^(3-)`
Oxidation state of Cr = +3
Electronic configuration of `Cr^(+3)=[Ar]3d^93)4s^(0)`

So, hybridisation of `[CrF_(6)[^(3-)3d=d^(2)sp^(3)`
Shape of molecule is octahedral.
(B) `XeF_(4)`
Number of `e^(-)` pair (Bond pair + lone pair)
Number of valence `e^(-)` + Number of univalent

So, for `XeF_(4)(n)=(8+4)/2=12/2=6`
`rArr` (4 bond pair + 2 lone pair)
It means `XeF_(4)` hybridisation `sp^(3)d^(2)` and square planar shape.
(C) `PCl_(5)`
b Number of `e^(-)` pair in `PCl_(5)(n)=(5+5)/2=10/2=5`
`rArr` (5 bond pair)
It means `PCl_(5)` hybridisation `sp^(3)d` and trigonal bipyramidal shapes.
(D) `BrF_(5)`
Number of `e^(-)` pair in `BrF_(5)(n)=(7+5)/2=12/2=6`
`rArr` (5 bond pair + 1 lone pair)
It means `BrF_(5)` hybridisation `sp^(3)d^(2)` and square pyramidal shape.
