Answer: C — To require drivers to come to a complete stop

The purpose of the "Stop" sign is to require drivers to come to a complete stop. This traffic control device is crucial for ensuring safety at intersections and pedestrian crossings, as it mandates that vehicles halt completely before proceeding. This action allows drivers to assess their surroundings for any oncoming traffic or pedestrians that may not be immediately visible, reducing the risk of accidents. The complete stop is an essential traffic rule that helps maintain order and safety on the road, making it clear that proactive measures are necessary before continuing on the route.
