Solution
The correct option is A Lead
Liquation is a refining method used to separate the impurities from the metal when the difference in the melting points of the metal and impurities is appreciable.
Pure metals having a low melting point can be heated on a slope where they melt and move down whereas the impurities remain on the top.
Metals such as tin and lead are usually refined by this process since they have low melting points.
