Angle of attack on a down going wing in a roll
- increases.
- decreases.
- unaffected.
Explanation from PART66Online
As a wing rolls, the down-going wing moves downward through the air, which adds an upward component to the relative airflow and increases its effective angle of attack. The up-going wing experiences the opposite. This difference produces extra lift on the down-going wing, giving the roll damping that opposes the motion.

Dihedral is an angle formed between the wing and a line parallel to the lateral axis (when u look at an aircraft from the nose, u can see the wings going up a little bit). This angle provides increased AOA for the down going wing during roll motions in order to provide stabilizing moments and return the aircraft to equilibrium.
