Solution

The correct options are
A $(C l F_{4} O)^{-}, (X e O F_{4})$
B $C l F_{3}, C l F_{3} O$
C $C l F_{3} O, C l F_{3} O_{2}$
Hybridisation = No. of lone pairs + No. of bonded atoms

For (A)
Hybridisation of $C l F_{3} = 3 + 2 = 5 (s p^{3} d)$
Hybridisation of $C l F_{3} O = 4 + 1 = 5 (s p^{3} d)$

For (B)
Hybridisation of $C l F_{3} O = 4 + 1 = 5 (s p^{3} d)$
Hybridisationof $C l F_{3} O_{2} = 5 + 0 = 5 (s p^{3} d)$

For (C)

Hybridisation of $C l F_{2} O^{+} = 3 + 1 = 4 (s p^{3})$
Hybridisation of $C l F_{4} O^{-} = 5 + 1 = 8 (s p^{3} d^{2})$

For (D)

Hybridisation of $C l F_{4} O^{-} = 5 + 1 = 8 (s p^{3} d^{2})$
Hybridisation of $X e O F_{4} = 5 + 1 = 6 (s p^{3} d^{2})$

So, the correct option is $C$
