Strategy:
 Identify the general formula () for each complex. Cis-trans (geometrical) isomerism occurs in octahedral complexes typically of the type , , or .

Step 1: Evaluate each complex
- (a) : Forms . This is an  type complex, which exhibits cis and trans isomers.
- (b) : Forms . This is an  type complex. No geometrical isomers possible.
- (c) : Forms . This is an  type complex. No geometrical isomers possible.
- (d) : Forms . Again, an  type complex. No geometrical isomers possible.
