Solution

The correct option is A CH4
The hybridisation on C in CH4 is sp3 - each hybrid orbital shows 25% s-character.
In XeO3 also, the hybridisation is sp3 (but has pyramidal shape with bond angle < 109.5 ), so that we expect 25% s-character for each hybrid orbital.
But % s-character depends on the bond angle(θ).
cos θ=ss1
scharacterbond angle
Thus, hybrid orbitals of CH4 will be having more s-character.
The hybrid orbitals of XeO46 having sp3d2 hybridisation shows approximately 16.7% s-character. SF4 having sp3d hybrid orbitals will show approximately 20% s-character.
