Two complexes $[Cr(H_2O)_6]Cl_3 \ (A)$ and $[Cr(NH_3)_6]Cl_3 \ (B)$ are violet and yellow coloured respectively. The incorrect statement regarding them is

Which of the following complexes has the maximum number of unpaired electrons in the $e_g$ set of orbitals?

Which of the following cannot be explained by crystal field theory?

In which one of the following complexes does the metal ion have a $t_{2g}^3 e_g^2$ configuration?

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

Given below are two statements:
Statement $I$: Presence of a large number of unpaired electrons in transition metal atoms results in higher enthalpies of their atomisation.
Statement $II$: $d_{xy} = d_{xz} = d_{yz} < d_{x^2-y^2} = d_{z^2}$ and $d_{x^2-y^2} < d_{xy} = d_{xz} = d_{yz}$ are the $d$-orbital splittings in $[Fe(H_2O)_6]^{3+}$ and $[Ni(Cl)_4]^{2-}$ complex ions respectively.
In the light of the above statements, choose the correct answer from the options given below:
