### Ligand-Field Stabilization Energies (LFSE) Overview

This table presents the ligand-field-stabilization energies (LFSE) in cm⁻¹ for three pairs of metal complexes, denoted as \([ML_6]^{3+}\) and \([ML_6]^{2+}\). These complexes are considered to understand the differences in LFSE between reduced (\([ML_6]^{2+}\)) and oxidized (\([ML_6]^{3+}\)) states. Below is the tabulated data reflecting the given energies:

| Complex             | \(\Delta_0\) (cm⁻¹) |
|---------------------|----------------------|
| \([Co(H_2O)_6]^{3+}\) | 16,750               |
| \([Co(H_2O)_6]^{2+}\) | 8,400                |
| \([Mn(H_2O)_6]^{3+}\) | 15,800               |
| \([Mn(H_2O)_6]^{2+}\) | 7,850                |
| \([Fe(H_2O)_6]^{3+}\) | 14,000               |
| \([Fe(H_2O)_6]^{2+}\) | 9,350                |

**Task:** Calculate the difference in LFSE for each pair, assuming \([ML_6]^{3+}\) complexes are low-spin and \([ML_6]^{2+}\) complexes are high-spin. The differences in LFSE should be arranged in increasing order of magnitude in cm⁻¹.

### Possible Order of LFSE Differences

Here are the given options for arranging the differences, in increasing magnitude:

- **A:** \(5,500\) (Fe\(^{2+}\)/Fe\(^{3+}\)) < \(9,580\) (Mn\(^{2+}\)/Mn\(^{3+}\)) < \(25,080\) (Co\(^{2+}\)/Co\(^{3+}\))
- **B:** \(560\) (Fe\(^{2+}\)/Fe\(^{3+}\)) < \(25,080\) (Co\(^{2+}\)/Co\(^{3+}\)) < \(25,280\) (Mn\(^{2+}\)/Mn\(^{
