Answer: B — U-turns are prohibited at this location

A "No U-Turn" sign clearly indicates that making a U-turn is prohibited at that specific location. This sign is essential for maintaining the flow of traffic and ensuring safety on the road. When drivers see this sign, they should know that attempting to turn their vehicle in a complete circle to go in the opposite direction is not allowed.
