The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Liquation Method: Pb, Sn, Bi, Zn etc are purified by this method. These metals have low melting point and the impurities have high melting point. In an open hearth, the metal is heated to its melting point and the metal melts down and impurities remain behind.

Hence, both assertion and reason are correct and reason is the correct explanation for assertion.
