What is the meaning of the following road marking (where there is a lay-by and curbstones)?

- A parking space for two-wheelers.
- Correct answer: Stopping is permitted for certain types of vehicles, as indicated in the signpost in place.
- Stopping in the marked area is permitted for all types of vehicles.
- A place where stopping is permitted for non-motor vehicles only.
Why this is the answer
The correct answer in the official bank: Stopping is permitted for certain types of vehicles, as indicated in the signpost in place.
A red-yellow marking along a lay-by and curbstones means that stopping there is permitted for a certain type of vehicle, as indicated in the sign placed there. So stopping there is not permitted for all types of vehicles. The marking is also not meant specifically for two-wheelers or for non-motor vehicles.
