With the ailerons away from the neutral, induced drag is
- higher on the lower wing plus profile drag also increases.
- unchanged but the profile drag is somewhat higher.
- higher on the upper wing plus profile drag increases.
Explanation from PART66Online
Deflecting ailerons raises lift on the up-going wing and lowers it on the down-going wing. Because induced drag grows with the lift a wing produces, the wing generating more lift (the rising, upper wing) generates more induced drag, and the increased deflection also adds profile drag. This drag asymmetry is what causes adverse yaw.

i think its wrong the lower wing during a turn has bigger angle of attack so the lower wing has more induced drag !!!

As we know upper wing in turn have ailerons down which leads for increase in lift, however induced drag is a lift drag, so higher or upper going wing have more induced drag and profile drag.

When ailerons are deflected away from neutral, the down going aileron increases the local camber and angle of attack, producing more lift and, consequently, more drag on that wing. As a result, the statement that completes your sentence correctly is :higher on the lower wing plus profile drag also increases. Why ?Moving the ailerons causes the wing with the down going aileron to generate more lift, which leads to a greater pressure differential and stronger wingtip vortices, thereby increasing induced drag. Additionally, the increased angle of attack and camber on that side disrupt the airflow and increase profile (form) drag
