Identify the correct statement from the following:

Given below are two statements.
Statement $I:$ During electrolytic refining,blister copper deposits precious metals.
Statement $II:$ In the process of obtaining pure copper by electrolysis method,blister copper is used to make the anode.
In the light of the above statements,choose the most appropriate answer from the options given below.

Match the elements in Column-$I$ with methods of purification in Column-$II$.

Column-$I$	Column-$II$
$(a)$ Boron	$(i)$ Van Arkel method
$(b)$ Tin	$(ii)$ Mond's process
$(c)$ Zirconium	$(iii)$ Liquation
$(d)$ Nickel	$(iv)$ Zone refining

Hoop's process is used for the purification of the metal:

The anode mud in the electrolytic refining of silver contains

The solubilities of the impurities in the melt and solid states are not the same. This principle is applied during the extraction of boron. This method is known as:
