Solution
Assertion and reason both are true but reason is not the correct explanation of assertion.
Explanation:
In the complexes, \[\ce{Co}\] exists as \[\ce{Co^{2+}}\] and \[\ce{Fe}\] as \[\ce{Fe^{2+}}\]. Both of the complexes becomes stable by oxidation of metal ion to \[\ce{Co^{3+}}\] and \[\ce{Fe^{3+}}\].
