For a tetrahedral complex of a metal in the first transition series, which of the following statements concerning energies of the 3d orbitals is correct?

(a) The five d orbitals have the same energy.

(b) The $d_{x^2}{}_{-y^2}$ and $d_{z^2}$orbitals are higher in energy than the d_xz, d_yz and d_xy orbitals.

(c) The d_xz, d_yz and d_xy orbitals are higher in energy than the $d_{x^2}{}_{-y^2}$and $d_{z^2}$orbitals.
