If the segmented bar graph indicates a significant increase in phone usage while driving on city roads compared to highways and rural roads, what could be a possible reason?

Frequent stops and slower traffic on city roads may give drivers more opportunities to look at or use their phones than they have on highways or rural roads. This makes “City roads offer more opportunities for distracted driving due to frequent stops” a plausible reason for the increase. The graph alone does not prove the cause, but the other choices either point to a different road type or assume a data error without evidence.
