Text Solution

Verified by Experts

The correct Answer is:
B
This process is used for the purification of the metal, which itself is readily fusible, but the impurities present in it are not, i.e., the impurities are infusible. This process is used for the purification of `Sn` and `Zn`, and for removing `Pb` from `Zn-Ag` alloy, which is obtained at the end of Parke's process and contains `Pb` as impurity.
