Find the sum of optically active Isomers of both $\left[\mathrm{Pt}(\text{ gly }{)}_2{\mathrm{Cl}}_2\right]$ and $\left[\mathrm{Co}(en{)}_2{\mathrm{Cl}}_2\right]$

cis isomers of both are optically active  $\left[\mathrm{M}(\mathrm{AB}{)}_2{\mathrm{Cl}}_2\right]$

$3\times 2=6$

Also $\left[\mathbf{M}(\mathrm{AA}{)}_2{\mathrm{Cl}}_2\right]$

$\text{ Total }=6+2=8$

Hence correct answer is 0008
