Downward displacement of an aileron
- increases the stalling angle of attack for that wing.
- decreases the angle at which its wing will stall.
- has no effect on its wing stalling angle, only on stalling speed.
Explanation
A downward-deflected aileron increases the local camber and effective angle of attack of that wing section, so the airflow separates at a lower geometric angle of attack. This lowers the stalling angle for that wing, which is why the down-going wing can stall first near the stall.

how come aileron effect the stall?

Because generally aileron controlls the roll of the a/c.This is a fact.So if the aileron moves the aircraft will roll.Depeding on the roll or the wing side,the angle will decrease or increase.In the particular question it says "downward " which means the aileron will move down so the a/c will probably roll and the side which turned down will decrease the angle.
