What is the meaning of the following traffic sign?

- Correct answer: Cab rank; no stopping and parking of other vehicles, except for unloading passengers.
- Pick-up stop; no stopping and parking of other vehicles.
- No stopping and parking for any vehicle within a distance of 20 meters.
- Route service station for special cabs and busses.
Why this is the answer
The correct answer in the official bank: Cab rank; no stopping and parking of other vehicles, except for unloading passengers.
This sign marks a cab rank. The yellow taxi roof sign shows the spot is reserved for taxis, and the red circle with a diagonal line bans other vehicles from stopping and parking there. A vehicle that is not a taxi may stop only briefly to let passengers get out. The ban does not cover every vehicle, because taxis themselves may wait at the rank.
