In the given complex, one ligand is monodentate (Cl) while the other is bidentate (H₂O and NH₃). Hence, the possible isomers are cis and trans. In cis isomer, two monodentate ligands (Cl and H₂O) are adjacent to each other while in trans isomer, they are opposite to each other. Looking at the formula, we can see that the Br ion is outside the brackets and hence, does not participate in isomerism. Therefore, the two isomers are [Pt(Cl)(H₂O)(NH₃)]Br (cis) and [Pt(Cl)(NH₃)(H₂O)]Br (trans). So, the correct statement is I is trans (trans isomer has nitrogen donor ligand trans to chloride) and II is cis (cis isomer has nitrogen donor ligand cis to chloride).
