Which of the following is the correct $\mathrm{CFSE}$ configuration for ${\left[{\mathrm{CoCl}}_4\right]}^{2-}$ complex:

[$\mathrm{p}$ = Pairing energy]

$$\begin{gathered} {\left[{\mathrm{CoCl}}_4\right]}^{2-} \\ \mathrm{Co} \Rightarrow \left[\mathrm{Ar}\right]3{\mathrm{d}}^{7}4{\mathrm{s}}^2 \\ {\mathrm{Co}}^{+2} \Rightarrow \left[\mathrm{Ar}\right]3{\mathrm{d}}^7 \end{gathered}$$

$$\begin{gathered} \mathrm{CFSE} = –0.6 {\mathrm{e}}_{\mathrm{g}}{\mathrm{es}}^{-} +0.4 {\mathrm{t}}_{2\mathrm{g}} {\mathrm{es}}^{-}+ \mathrm{mp} \\ = – 0.6 \times 4 + 0.4 \times 3 + 2\mathrm{p} \\ = –1.2 + 2\mathrm{p} \end{gathered}$$
