Interpretation: The given terms has to be explained.

Concept Introduction:

Crystal field theory: When ligands approach the central metal atom then the field strength of the ligand splits the outermost valence d orbitals of the central metal atom into two set of orbitals such as ${\text{t}}_{\text{2g}}$ and ${\text{e}}_{\text{g}}$ orbitals. The energy gap between two set of ${\text{t}}_{\text{2g}}$ and ${\text{e}}_{\text{g}}$ orbitals will be more or less based on the extent of splitting which in turn is based on the strength of the ligands. This phenomenon is known as Ligand field splitting.

The following diagram shows the splitting in the octahedral complexes:
