K4[Fe(CN)6] Fe ground state: [Ar]3d6 4s2 Fe2+: 3d6 4s0

Q. What is the correct electronic configuration of the central atom in $K_{4} [F e (CN)_{6})$ based on crystal field theory ?

$e^{3} t_{2}^{3}$

$e^{4} t_{2}^{2}$

$t_{2 g}^{4} e_{g}^{2}$

$t_{2 g}^{6} e_{g}^{0}$

$K_{4} [F e (CN)_{6}]$
Fe ground state: $[A r] 3 d^{6} 4 s^{2}$
$F e^{2 +} : 3 d^{6} 4 s^{0}$
