The answer is

A. Iron loses three electrons.

I just took the test and this is the correct answer.

Alma Conway · Answer 2

Answer: Iron loses three electrons and oxygen gain two electrons.

Explanation:

this reaction represents the formation of rust of Fe.

4Fe + 3O2 → 2Fe2O3

The Fe is oxidized by oxygen and converts from Fe (oxidation number = 0) to Fe3 + (oxidation number = 3+) that Fe loses 3 electrons. The oxygen is reduced and the oxidation state changed from 0 to 2 - that oxygen loses 2 electrons. The other 2 choices are clear to be wrong.
