The Correct Option is A

Solution and Explanation

In the coordination compound [Pt(NH3)2Cl(NO2)], the ligands are named in alphabetical order: "diammine" (for the two NH3 groups), followed by "chlorido" (for Cl) and "nitrito-N" (for NO2 attached via nitrogen). The oxidation state of platinum here is +2, denoted as "(II)" in the name. Therefore, the IUPAC name is "Diamminechloridonitrito-N-platinum(II)".
