C Correct answer
Explanation

Hg is extracted by cyanide reduction method. K is extracted by electrolysis of fused salts, usually chlorides. Pb metal is extracted by carbon reduction method. Zn metal is extracted by the reduction with Al thermite process. Hence, the correct answer using the codes is P - 3, Q - 1, R - 4, S - 2.
