(A) According to the Hard and Soft Acids and Bases $(HSAB)$ principle,soft bases like the sulphide ion $(S^{2-})$ prefer to bond with soft acids (metals).$Pb$ and $Ag$ are soft acids and commonly exist in the form of sulphide ores,such as $PbS$ (galena) and $Ag_{2}S$ (argentite).$Al$ is a hard acid and is mainly found in the form of oxide ores (e.g.,bauxite,$Al_{2}O_{3} \cdot 2H_{2}O$).$Mg$ is a hard acid and is typically found in the form of halide or carbonate ores (e.g.,carnallite,$KCl \cdot MgCl_{2} \cdot 6H_{2}O$).Therefore,only $(a)$ and $(c)$ form common sulphide ores.

$(a)$ $Pb$ $(b)$ $Al$ $(c)$ $Ag$ $(d)$ $Mg$
