there is no way it can be A b/c you never punched a hole all the way on the left side of the square. also the number of layers of paper where the hole was punched is 6 so there must be six holes on the final unfold.
Where did you get this question? Its not B either. There would only be 4 holes ... two right in the middle of the lowest row and two right above that layer.
