When you come to an intersection with a divided highway or a roadway with three or more lanes, you must do what?

Answer: B — Yield the right-of-way to other traffic

In the context of an intersection with a divided highway or a roadway that has three or more lanes, yielding the right-of-way to other traffic is essential for safe navigation. When multiple lanes are involved, or when dealing with a divided highway, it's common for vehicles to be approaching from various directions. Therefore, exercising caution and yielding allows for safe merging and crossing, minimizing the risk of accidents. Yielding the right-of-way means giving priority to vehicles that are already in the intersection, or those that are arriving at the intersection concurrently. This is particularly important in complex traffic situations, where pedestrians or cyclists may also be present. By yielding, you ensure that all road users can move through the intersection safely, thus facilitating a smoother flow of traffic. Speeding up to avoid traffic can create dangerous situations, and simply proceeding on a green light without regard for other vehicles can lead to accidents, particularly in busy intersections. Making a U-turn is typically not a standard maneuver at such intersections unless explicitly permitted, and could also result in hazardous conditions. Thus, yielding the right-of-way is the most prudent and safe action.
