Given below are two statements : Statement I : Presence of large number of unpaired electrons in transition metal atoms results in higher enthalpies of their atomisation.Statement II : $\displaystyle \mathrm{d}_{x y}=\mathrm{d}_{x z}=\mathrm{d}_{y z}<\mathrm{d}_{x^2-y^2}=\mathrm{d}_{z^2}$ and $\displaystyle \mathrm{d}_{x^2-y^2}=\mathrm{d}_{z^2}<\mathrm{d}_{x y}=\mathrm{d}_{x z}=\mathrm{d}_{y z}$ are the d-orbital splittings in $\displaystyle \left[\mathrm{Fe}\left(\mathrm{H}_2 \mathrm{O}\right)_6\right]^{3+}$ and $\displaystyle \left[\mathrm{Ni}(\mathrm{Cl})_4\right]^{2-}$ complex ions respectively. In the light of the above statements, choose the correct answer from the options given below :
