Correct answer: D. Step 1: Check for other types of isomerism: there are no ambidentate ligands (ruling out linkage), no coordinated water molecules (ruling out hydrate), and no counterions to exchange (ruling out ionization). Step 2: The complex has the general formula [MA2B2C2]^-. Step 3: Such octahedral systems with three pairs of identical ligands can form multiple structurally distinct arrangements (cis/trans and fac/mer configurations) via geometrical isomerism, which corresponds to option (b).
