The  element  that has  been  oxidized   is Al  (  Answer  A)


Explanation

 if  the oxidation number of an element is greater in the product side than the reactant  side  then the element   has lost  the electrons . This mean  that  the element  has been oxidized.

Al  is  oxidized  because  it move  from  oxidation  state  Zero(0)  in reactant side  to  oxidation state 3⁺  in product  side.

This  implies  that  Al  loses  3  electrons.
