Which one of the following is an incorrect statement pertaining to the properties of Coordination compounds?

A square planar complex of the type Mabcd, where a, b, c and d are unidentate ligands, exhibits geometrical isomerism and exists in one cis-form and two trans-forms.

[$$\mathrm{Co}\left(\mathrm{NH}_3\right)_5 \mathrm{NO}_2$$] Cl₂ exists in 2 forms, the red form and the yellow form which are linkage isomers.

$$\left[\mathrm{Fe}(\mathrm{CN})_6\right]^{3-}$$ is called a Low spin complex.

Out of cis- $$\left[\mathrm{CrCl}_2(\mathrm{ox})_2\right]^{3-}$$ and trans- $$\left[\mathrm{CrCl}_2(\mathrm{ox})_2\right]^{3-}$$, the trans isomer is optically inactive.
