When does a pedestrian have the right-of-way?

Answer: C — At marked crosswalks

Pedestrians have the right-of-way at marked crosswalks because these areas are specifically designated for pedestrians to cross the road safely. At all intersections, whether marked or unmarked, pedestrians must still follow traffic signals and yield to oncoming vehicles. Similarly, at designated spots on the road, such as intersections with stop signs or yield signs, pedestrians must also yield to vehicles. Therefore, marked crosswalks are the only option where pedestrians have the undisputed right-of-way.
