In which of the following complexes, magnetic moment will change when all the ligands are replaced by ${\mathrm{CN}}^{-}$ ion to form a cyano complex?

Out of the following four complexes of $\mathrm{Ni}$, the complexes which will be attracted by magnetic field are:

(I) ${\left[\mathrm{Ni}{\left(\mathrm{CN}\right)}_4\right]}^{2-}$

(II) ${\left[{\mathrm{NiCl}}_4\right]}^{2-}$

(III) $\left[\mathrm{Ni}{\left(\mathrm{CO}\right)}_4\right]$

(IV) ${\left[\mathrm{Ni}{\left({\mathrm{H}}_2\mathrm{O}\right)}_6\right]}^{2+}$

What is the correct order of magnetic moments (spin values in $\mathrm{BM}$) among ${\left[{\mathrm{MnCl}}_4\right]}^{2-}$, ${\left[\mathrm{Fe}{\left(\mathrm{CN}\right)}_6\right]}^{4-}$and ${\left[{\mathrm{CoCl}}_4\right]}^{2-}$?

(atomic number: $\mathrm{Mn}=25, \mathrm{Fe}=26, \mathrm{Co}=27$)
