The reaction for obtaining the metal (M) from its oxide \(\left(\mathrm{M}_{2} \mathrm{O}_{3}\right)\) ore is given by \(\mathrm{M}_{2} \mathrm{O}_{3}(\mathrm{~s})+2 \mathrm{Al}(\ell) \stackrel{\mathrm{Heat}}{\longrightarrow} \mathrm{Al}_{2} \mathrm{O}_{3}(\ell)+2 \mathrm{M}(\mathrm{s}),(\mathrm{s}=\) solid, \(\ell=\) liquid \()\)
in that case, \(M\) is
(A) Copper
(B) Calcium
(C) Iron
(D) Zinc
