With reference to differential aileron control
- drag decreases on the outer wing.
- drag increases on the outer wing.
- drag increases on the inner wing.
Explanation
Differential ailerons are rigged so the up-going aileron deflects more than the down-going one. In a turn the inner (down-going) wing has the up aileron raised more, increasing its drag, which helps counter adverse yaw - the tendency to yaw away from the turn. So drag increases on the inner (down-going) wing, balancing the yawing moment from the lift change.
huatwu asking:
why the answer is not drag decrease on the outer wing since when in a roll... drag will increase on the outer wing....

the raised aileron has as much or more surface area exposed to the airflow thus increased drag
