What is the correct electronic configuration of the central atom in \( \mathrm{K}_{4}\left[\mathrm{Fe}(\mathrm{CN})_{6}\right] \) based on crystal field theory?
(NEET 2019)
\( \mathrm{P} \)
(a) \( e^{4} t_{2}^{2} \)
(b) \( t_{2}^{4} e_{g}^{2} \)
W
(c) \( t_{2 g}^{6} e_{g}^{0} \)
(d) \( e^{3} t_{2}^{3} \)
