D. Cross traffic and oncoming traffic are stopped with a red light.
Explanation:
A protected turn happens when there is a green arrow allowing you to safely proceed at a signal-controlled intersection. The green arrow indicates that any other traffic (cars, bicycles, pedestrians, etc.) that could somehow conflict with you is halted by red signals. Of course, once the arrow turns green, it is your duty to wait for any car, pedestrian or bicycle that may be still crossing or coming your way to pass.
Adaptive behaviour refers to the skill set (conceptual, social and practical) that allows an individual to affront daily life circumstances. That's why IDEA defines it like that.
