What is the meaning of the following traffic sign?

- Promenade ahead.
- Path for cyclists only.
- Correct answer: Path for cyclists and pedestrians only.
- Crossing for cyclists and pedestrians.
Why this is the answer
The correct answer in the official bank: Path for cyclists and pedestrians only.
A round blue sign is a mandatory sign that reserves a way for a certain type of user. Showing both pedestrians and a bicycle means the path is meant only for cyclists and pedestrians, so motor vehicles may not use it. A crossing is indicated by different signs and road markings, not by a round blue sign like this.
