(B) The van Arkel method is a technique for refining metals. In this process,the impure metal is heated with iodine at a lower temperature to form a volatile metal iodide. However,at a very high temperature like $1700 \ K$,the metal iodide is unstable and decomposes back into the metal and iodine. Therefore,no stable iodide product is formed at this temperature,and the reaction effectively does not proceed to form the desired iodide product.

In van Arkel method,if $I_2$ is introduced at $1700 \ K$ over impure metal,the product will be :
