The correct answer is:
A - III, B - IV, C - II, D - I
Zone refining is done for semiconductors and so $\mathrm{A}$ $\rightarrow$ III. Poling is done for metals like $\mathrm{Cu}$ along with other steps like blistering and cupellation.
Thus, $\mathrm{B} \rightarrow$ IV.
Liquation is done for metals like $\mathrm{Sn}$ in which it is partially melted and separated.
Thus, $\mathrm{C} \rightarrow$ II.
Vapour phase refining is done for metals that form volatile compounds like $\mathrm{Ni}, \mathrm{Ti}, \mathrm{Zr}$, etc.
Thus, $\mathrm{D} \rightarrow \mathrm{I}$.
Thus, $\mathrm{B} \rightarrow$ IV.
