The number of possible isomers of an octahedral complex $[Co(C_2O_4)_2(NH_3)_2]^-$ is

Which coordination number is associated with geometric isomerism in coordination compounds?

Which of the following complex species is not expected to exhibit optical isomerism?

An octahedral complex having molecular composition $Co \cdot 5NH_3 \cdot Cl \cdot SO_4$ has two isomers $A$ and $B$. The solution of $A$ gives a white precipitate with $AgNO_3$ solution and the solution of $B$ gives a white precipitate with $BaCl_2$ solution. The type of isomerism exhibited by the complex is,
