A complex containing cobalt(III) ion is associated with two diaminopropane molecules and two chloride ion forming an octahedral geometry. The complex ion will show :

A complex containing cobalt (III) ion is associated with two diaminopropane molecules and two chloride ion forming an octahedral geometry. The complex ion will show identical except for a ligand has exchanged places with an anion or neutral molecule that was originally outside the coordination complex.

Hence, options A, B and C are correct.
