पर्याय
\[\ce{[Fe(CO)5]}\]
\[\ce{[Fe(CN)6]^{3-}}\]
\[\ce{[Fe(C2O4)3]^{3-}}\]
\[\ce{[Fe(H2O)6]^{3+}}\]

उत्तर
\[\ce{[Fe(C2O4)3]^{3-}}\]
Explanation:
Chelation (formation of cycle by linkage between metal ion and ligand) stabilizes the coordination compound. The ligand which chelates the metal ion are known as chelating ligand.
Here, only \[\ce{[Fe(C2O4)3]^{3-}}\] is a coordination compound which contains oxalate ion as a chelating ligand.
Hence, it stabilizes coordination compound by chelating \[\ce{Fe^{3+}}\] ion.
