Given below are two statements:
Statement I: The number of paramagnetic species among $\displaystyle \left[\mathrm{CoF}_6\right]^{3-},\left[\mathrm{TiF}_6\right]^{3-}$, $\displaystyle \mathrm{V}_2 \mathrm{O}_5$ and $\displaystyle \left[\mathrm{Fe}(\mathrm{CN})_6\right]^{3-}$ is $\displaystyle 3$ .Statement II:
$\displaystyle \mathrm{K}_4\left[\mathrm{Fe}(\mathrm{CN})_6\right]<\mathrm{K}_3\left[\mathrm{Fe}(\mathrm{CN})_6\right]<\left[\mathrm{Fe}\left(\mathrm{H}_2 \mathrm{O}\right)_6\right] \mathrm{SO}_4 . \mathrm{H}_2 \mathrm{O}<\left[\mathrm{Fe}\left(\mathrm{H}_2 \mathrm{O}\right)_6\right] \mathrm{Cl}_3$ is the correct order in terms of number of unpaired electron(s) present in the complexes.In the light of the above statements, choose the correct answer from the options given below
