The correct answer is: A mixture of $\mathrm{Al}_2 \mathrm{O}_3$ and carbon in dry $\mathrm{Cl}_2$ gas
$\mathrm{Al}_2 \mathrm{O}_3$ may be converted to anhydrous $\mathrm{AlCl}_3$ by heating a mixture of $\mathrm{Al}_2 \mathrm{O}_3$ and carbon in dry chlorine.
$\mathrm{Al}_2 \mathrm{O}_3+3 \mathrm{C}+3 \mathrm{Cl}_2 \rightarrow \underset{\text {(anhydrous } \mathrm{AlCl}_3)}{\mathrm{Al}_2 \mathrm{Cl}_6}$
