Answer: (B)

A sign indicating "stop bus ahead" signifies that a bus is expected to stop in the vicinity to either pick up or drop off passengers. This is a crucial warning for drivers to prepare for potential pedestrian activity around the bus. When buses stop, it is common for passengers, including children, to board or exit the vehicle, which increases the chances of unexpected movements in or near the roadway.

In recognizing this sign, drivers in the area should approach with heightened awareness and reduced speed, allowing for safe passage as individuals may be crossing the street. The communication of this warning helps in maintaining safety on the road, as it prompts drivers to stay alert for any passengers who might be near the bus.
