D Correct answer
Explanation

This option is correct because the complexes cis and trans [PtA2X2] react with thiourea to give substituted product [Pt(tu)4]2+but Cl is replaced by NH3 to form [Pt(NH3)2(tu)2]2+. This is used in the thiourea reaction to the assigned structure, which is known as Kurnakov test.
