Movement about the vertical axis is yaw, controlled by which surface?

Explanation:
Yaw is rotation about the vertical axis, and the rudder is the control surface that governs this motion. The rudder sits on the vertical tail and, when you press the pedals, it deflects left or right. This creates a difference in air pressure behind the tail that pushes the nose in the corresponding direction, producing a yawing moment. Elevators move the nose up or down (pitch about the lateral axis), ailerons tilt the wings to roll (rotation about the longitudinal axis), and flaps increase lift and drag during takeoff or landing. So the surface responsible for yaw is the rudder.
