Given below are two statements:

$$\textbf{Statement I :}$$ Presence of large number of unpaired electrons in transition metal atoms results in higher enthalpies of their atomisation.

$$\textbf{Statement II :}$$ $$d_{xy} = d_{xz} = d_{yz} < d_{x^2-y^2} = d_{z^2}$$ and $$d_{x^2-y^2} = d_{z^2} < d_{xy} = d_{xz} = d_{yz}$$ are the d-orbital splittings in $$[\text{Fe}(\text{H}_2\text{O})_6]^{3+}$$ and $$[\text{Ni}(\text{Cl})_4]^{2-}$$ complex ions respectively.

In the light of the above statements, choose the correct answer from the options given below:
