Answer:

At standard temperature and pressure:
#16Al (s) + 3S_8(s) -> 8Al_2S_3 (s)#

Explanation:

See above. Aluminum(III) Sulfide is #Al_2S_3# which is also solid at standard temperature and pressure.

We know that the suflide ion has a charge of #2-#, and we are told aluminum has a charge of #3+#. The above formula is the only option.
