A)On roads with priority.
B)On roundabouts.
C)On stretches of road where overtaking is prohibited.Correct
# Explanation
The prohibition on changing the direction of travel applies in stretches where overtaking is prohibited, since these areas have limited visibility or road characteristics that make reverse maneuvers dangerous. This restriction is indicated by a double continuous line and ensures the safety of all users. Conversely, on roads with priority and in roundabouts there are specific regulations that do not imply a general prohibition on changing direction.
