Identify the metal \( \mathrm{M} \) whose extraction is based on the following reactions:
\[
\begin{array}{l}
\mathrm{MS}+2 \mathrm{O}_{2} \rightarrow \mathrm{MSO}_{4} \\
2 \mathrm{MS}+3 \mathrm{O}_{2} \rightarrow 2 \mathrm{MO}+2 \mathrm{SO}_{2} \\
\mathrm{MS}+2 \mathrm{MO} \rightarrow 3 \mathrm{M}+\mathrm{SO}_{2} \\
\mathrm{MS}+\mathrm{MSO}_{4} \rightarrow 2 \mathrm{M}+2 \mathrm{SO}_{2}
\end{array}
\]
(a) Magnesium
(b) Aluminium
(c) Lead
