From an octahedral splitting arrangement if two ligans present along Z-axis are removed then what will be the correct order of energy for 5d-orbitals of central metal?

The correct order of energies of d-orbitals of metal ion in a square planar complex is

The correct order of energies of d-orbitals of metal ion in a square planar complex is

According to cystal field theory, interaction between central metal atom/ion and ligand is electrostatic in nature. In free metal ions, the five d-orbitals are degenerate. However, in a ligand field e.g., tetrahedral, octahedral, square planar, square pyramidal, trigonal bipyramidal, the degeneracy of 5d-orbitals is lost. If lobes of d-orbitals of central metal atom/ion are along the axes through which ligands are approaching, the energy of corresponding d-orbital is raised more than the d-orbitals having lobes between teh axes. e.g., octahedral complexes, square planar complexes, square pyramidal compexes. The correct order Delta_(o), Delta_(t)" and "Delta_(sp) (where o, t and sp stand for octahedral, tetrahedral and square planar fileds respectively) is :
