Simplified absorption spectra of three complexes  (i),(ii)  and (iii)  of  $M^{+n}$  ion are provided below , their  ${\lambda }_{\max }$     Values  are correct match between the complexes and their ${\lambda }_{\max }$   values is 

i)  [M(CN)₆ ]^(-6+n)     ii)  ${\left[MC{l}_6\right]}^{-6+n}$    iii)  [M(NO_2)6]^-6+n
