Simplified absorption spectra of three complexes ((i), (ii) and (iii)) of $\mathrm{M}^{n^{+}}$ion are provided below; their $\lambda_{\max }$ values are marked as A , B and C respectively. The correct match between the complexes and their $\lambda_{\max }$ values is

(i) $\left[\mathrm{M}(\mathrm{NCS})_6\right]^{(-6+n)}$
(ii) $\left[\mathrm{MF}_6\right]^{(-6+\mathrm{n})}$
(iii) $\left[\mathrm{M}\left(\mathrm{NH}_3\right)_6\right]^{\mathrm{n}+}$
