At an intersection with stop signs on all four corners, unless otherwise posted, who has the right-of-way?

Answer: B — Traffic on the left

In an intersection with stop signs on all four corners, it is important to yield to other vehicles before proceeding. This is because all four directions technically have equal rights to proceed as long as they come to a complete stop and follow other traffic laws. However, the vehicle on the left has the right-of-way as they are typically the first to enter the intersection and have a clearer view of oncoming traffic from the right. Pedestrians in the crosswalk should also be given the right-of-way as they have the most vulnerable position in this scenario. The driver who gets there first may technically have an advantage, but it is always safest to yield to oncoming vehicles and pedestrians in order to avoid potential accidents. Thus, option B is the correct answer.
