Strategy:
 Check the stereochemical capability of each complex formula to occupy completely opposite () positions with identical or similar ligands.

Step 1: Evaluate each complex
- : All bidentate ligands. A trans arrangement of bridging oxalates or en across  is physically impossible due to string-strain. No trans isomer.
- : Square planar. The en ligand spans only  (cis). Thus, the two  must occupy the remaining two cis positions. No trans isomer.
- : Tetrahedral. There are no  positions in a
