Answer: (C)

Holding a red flag or sign is widely recognized as a universal signal for danger or a hazardous condition on a work site. The color red is often associated with alertness and warnings, which makes this signal clear and effective in conveying the necessity for caution. It draws immediate attention from workers and operators, indicating that they should proceed with care or stop altogether if needed. This use of a visually distinct warning signal helps in communicating potential risks quickly and effectively, ensuring safety on the job site.
