Frise-type aileron is a type of which control surface?

Explanation:
Frise-type describes a modification of the aileron. Ailerons are the control surfaces that move in opposite directions on the wings to produce roll about the aircraft’s longitudinal axis. In a Frise-type design, the lower part of the aileron projects below the wing trailing edge as it deflects, increasing drag on the wing that’s moving up and helping to create adverse yaw to aid coordination and control. The elevator controls pitch, the rudder controls yaw, and spoilers are separate devices that disturb lift, not a Frise-type aileron.
