The correct order for wavelengths of light absorbed in the complex ions $[CoCl(NH_3)_5]^{2+}$, $[Co(NH_3)_6]^{3+}$, and $[Co(CN)_6]^{3-}$ is

Question

$[CoCl(NH_3)_5]^{2+} > [Co(NH_3)_6]^{3+} > [Co(CN)_6]^{3-}$

$[Co(NH_3)_6]^{3+} > [Co(CN)_6]^{3-} > [CoCl(NH_3)_5]^{2+}$

$[Co(CN)_6]^{3-} > [CoCl(NH_3)_5]^{2+} > [Co(NH_3)_6]^{3+}$

$[Co(NH_3)_6]^{3+} > [CoCl(NH_3)_5]^{2+} > [Co(CN)_6]^{3-}$
