Option (B) Set of d-orbitals which is used by central metal during formation of MnO4− is dxy,dyz,dxz. In spherical field of four oxide ligands, the five d orbitals are degenerate. They split into t2g and eg levels in tetrahedral field. The three t2g orbitals mix with 4s orbital to form d3s hybrid orbitals.
