b. [Ni (NH3) 3Br]Cl and [Ni (NH3) 3Cl]Br are a pair of ionization isomers.

Explanation:

Ionization isomers are those coordination compounds which produce different cations and anions in solutions.

Example: [Ni (NH3) 3Br]Cl produces Cl - anion in the solution while [Ni (NH3) 3Cl]Br produces Br - anion in the solution and hence [Ni (NH3) 3Br]Cl [Ni (NH3) 3Cl]Br are a pair of ionization isomers.
