Answer: (A)

Garrett Morgan is credited with inventing the traffic signal. He developed a version of the traffic light in 1923 that included an innovative design featuring three positions: stop, go, and an interval that allowed for vehicles to clear intersections before the light changed. His invention aimed to improve road safety and traffic efficiency, addressing the increasing number of vehicles on the roads during that era.

Morgan's contributions are particularly significant because they came at a time when traffic accidents were increasing, reflecting the need for a more organized approach to vehicular movement. His design laid the foundation for modern traffic lights, which have since evolved but still incorporate the basic principles that he established. This invention has had a lasting impact on urban planning and public safety, showcasing how one individual's creativity can contribute to societal advancements.
