How does the magnitude of ∆ o decide the actual configuration of d orbitals in a coordination entity?

Options

1. A∆ o determines the size of the d orbitals, which in turn dictates their arrangement in the coordination entity
2. B∆ o determines the energy difference between the lower and higher energy d orbitals, influencing their occupan
3. C∆ o has no impact on the configuration of d orbitals in a coordination entity.
4. D∆ o influences the shape of the coordination entity but not the configuration of d orbitals.
