What is the meaning of the following traffic sign?

- One-way roadway ahead.
- Correct answer: It is permitted to drive in this lane.
- Driving in this lane is prohibited.
- You have right-of-way on the road ahead
Why this is the answer
The correct answer in the official bank: It is permitted to drive in this lane.
A green arrow pointing down above a lane means the lane below it is open and you may drive in it. A red X above a lane, by contrast, means driving in it is prohibited. The sign does not indicate a one-way roadway and does not give you right-of-way.
