What is the meaning of the following traffic sign?

- Path for bicycles and motorcycles.
- Path for bicycles only.
- Correct answer: One-way lane for bicycle.
- No entrance for bicycles.
Why this is the answer
The correct answer in the official bank: One-way lane for bicycle.
The sign shows a bicycle beside a broken line, and it indicates a lane for cyclists in one direction. It has no motorcycle on it, so it is not a path shared by bicycles and motorcycles. It is also not a prohibition sign: no entrance for bicycles is shown by a round sign with a red border.
