(D) The correct statement analysis is as follows:$1$. Zinc is amphoteric and reacts with $NaOH$ to form sodium zincate: $Zn + 2NaOH \rightarrow Na_2ZnO_2 + H_2$. This statement is correct.$2$. Carbon monoxide acts as a reducing agent in the blast furnace: $Fe_2O_3 + 3CO \rightarrow 2Fe + 3CO_2$. This statement is correct.$3$. Mercury $(II)$ iodide dissolves in excess $KI$ to form a soluble complex: $HgI_2 + 2KI \rightarrow K_2[HgI_4]$. This statement is correct.$4$. Tin $(IV)$ chloride $(SnCl_4)$ is prepared by the action of dry chlorine gas on tin metal $(Sn + 2Cl_2 \rightarrow SnCl_4)$. Dissolving tin in concentrated $HCl$ produces tin $(II)$ chloride $(SnCl_2)$,not tin $(IV)$ chloride. Therefore,this statement is incorrect.
