In the reaction, aluminum (Al) loses electrons to form Al3+ ions and therefore, it is oxidized. On the other hand, each bromine atom in Br2 gains an electron to form bromide ion (Br−) and hence, it is reduced. Therefore, in the given reaction, Br2 is reduced to Br− and Al is oxidized, making option A the correct answer.
