Arrange the following Cobalt complexes in the order of increasing Crystal Field Stabilization Energy \((CFSE)\) value. Complexes : \(\left[\mathrm{CoF}_{6}\right]^{3-},\left[\mathrm{Co}\left(\mathrm{H}_{2} \mathrm{O}\right)_{6}\right]^{2+},\left[\mathrm{Co}\left(\mathrm{NH}_{3}\right)_{6}\right]^{3+}\) and \(\left[\mathrm{Co}(\mathrm{en})_{3}\right]^{3+}\) \(\quad\quad\quad\quad\quad\quad A\quad\quad\quad\quad \quad B\quad\quad\quad\quad\quad\quad C\quad\quad\quad\quad\quad\quad D\) Choose the correct option:

1. A \(\mathrm{A}<\mathrm{B}<\mathrm{C}<\mathrm{D}\)
2. B \(\mathrm{B}<\mathrm{A}<\mathrm{C}<\mathrm{D}\)
3. C \(\mathrm{B}<\mathrm{C}<\mathrm{D}<\mathrm{A}\)
4. D \(\mathrm{C}<\mathrm{D}<\mathrm{B}<\mathrm{A}\)
