A d-block metal $\mathrm{M}$ forms two complexes with the formulae${\mathrm{MCl}}_4.2\mathrm{HCl}$ and ${\mathrm{MCl}}_2.2{\mathrm{NH}}_3$. When excess of $AgN{O}_3$ solution is added to $1$ mole of each complex, $AgCl$precipitate is not formed. The secondary valency of metal $\mathrm{M}$ in the complexes is respectively

The complexes ${\left[\mathrm{Co}{\left({\mathrm{NH}}_3\right)}_6\right]}^{3+}3{\mathrm{Cl}}^{-}$ and ${\left[\mathrm{CoCl}{\left({\mathrm{NH}}_3\right)}_5\right]}^{2+}2{\mathrm{Cl}}^{-}$ have $\underline{ }$ colors respectively

The most stable complex among the following is _______
