In which of the following set of molecules central atoms are ${\mathrm{sp}}^3$ hybridised?

${\mathrm{SP}}^3$is the hybridization of ${\mathrm{NH}}^2$. Due to this, there will be six couples instead of five: two with hydrogen and two lone individuals. ${\mathrm{PCl}}^3$ is hybridised with${\mathrm{sp}}^3$ The ${\mathrm{PCl}}^{-}$ bonds are essentially created when the chlorine's single-occupied 3p orbitals and the ${\mathrm{sp}}^3$  hybrid orbitals overlap. Each chlorine atom also contains three lone pairs. In total, there are 3 electron pairs, 3 bond pairs, and 1 single pair of electrons in ${\mathrm{PCl}}^3$ .
Since the carbon atom in the ion ${\mathrm{CH}}^{3+}$ is sp2 hybridised, the geometry surrounding it is triangular planar. The H-C-H bond angle in this instance is 120°.
