Step-by-step solution

Statement I is correct. cis - [Pt(NH₃)₂Cl₂] , known as cisplatin, is used in the treatment of cancer to inhibit the growth of tumors. Statement II is correct. A mixture of titanium tetrachloride ( TiCl₄ ) and triethylaluminium ( Al(C₂H₅)₃ ) is known as Ziegler-Natta catalyst, which is used in the polymerization of ethene. Statement III is correct. In black and white photography, the developed film is fixed by washing with hypo solution ( Na₂S₂O₃ ) which dissolves the unexposed silver bromide to form a soluble compl
