  • A
    A - IV, B - II, C - I, D - III
  • B
    A - III, B - I, C - IV, D - II
  • Correct answer
    C
    A - III, B - IV, C - II, D - I
  • D
    A - II, B - IV, C - I, D - III

Solution

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, $\mathrm{D} \rightarrow \mathrm{I}$.

Hence, the correct answer is option: 'C'.
