In which of the following,complex ions are not in correct order with respect to their magnitude of crystal field splitting?

$A$ strong field ligand gives a complex which is generally called:

Simplified absorption spectra of three complexes $(i), (ii)$ and $(iii)$ of $M^{n+}$ 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
$(i)$ $[M(NCS)_6]^{(-6+n)}$
$(ii)$ $[MF_6]^{(-6+n)}$
$(iii)$ $[M(NH_3)_6]^{n+}$

Which sets of the $d$-orbitals are directly oriented towards the ligands in octahedral coordination compounds?

Match the following complexes in List-$I$ with their electronic configurations in List-$II$.
