Dear Student

The given redox reaction is :

8Al + 3Fe3O4 → 4Al2O3 + 9Fe o
s     0          +8/3              +3           0So the oxidation occur in Al and reduction in Fe3O4 So the change in oxidation number of 1 Al atom is 3 So, Change in 8 atom will be 24 electrons

So the correct option is (4)
