Answer: the balanced equation is 2Fe2O3 + 3C → 4Fe + 3CO2

Explanation:

The first equation to be balanced should be 4Al + 3O2 → 2Al2O3. The second equation to be balanced should be N2 + 3H2 → 2NH3. The third equation to be balanced should be 2CH4 + 4O2 → 2CO2 + 4H2O. The fourth choice is balanced and is the right answer.
