The correct answer is: High melting metal are refined by liquation
Liquation method is used for refining of such impure metals that are readily fusible (having low melting points) such as $\mathrm{Pb}, \mathrm{Sn}, \mathrm{Bi}$ and $\mathrm{Hg}$ as compared to impurities (less fusible).

The other queen statements are correct.
Hence, option (d) is incorrect.
