Square planar geometry does not allow for chiral centers, so optical isomerism is not possible. Geometric isomerism is possible if there are two different groups on adjacent positions of the square, and coordination isomerism is possible if the ligands attached to the metal ion can be interchanged to give a different compound. Linkage isomerism is possible if the ligand can bind to the metal ion through different atoms. Therefore, only option B is never possible.
