B)The bus.
C)The car towing the trailer.Correct
On a very narrow stretch of road where there is no priority signage, the vehicle that entered first has right of way.
In case of doubt about who entered first, priority goes to the vehicle with the greatest difficulty manoeuvring. The order of priority among the different types of vehicles when one of them must reverse is as follows:
1. Special vehicles and transport exceeding the established weights or dimensions.
2. Vehicle combinations, except those in point 4.
3. Animal-drawn vehicles.
4. Cars towing trailers of up to 750 kilograms GVW and motorhomes.
5. Vehicles used for collective passenger transport (buses).
6. Lorries, articulated lorries and vans.
7. Cars and car derivatives.
8. Special vehicles not exceeding the established weights or dimensions, quadricycles and light quadricycles.
9. Three-wheeled vehicles, motorcycles with sidecars and three-wheeled mopeds.
10. Motorcycles, two-wheeled mopeds and bicycles.
When the vehicles are of the same type or of a type not listed above, right of way is decided in favour of the one that has to reverse the greater distance, and, in the event of a tie, in favour of the one with the greater width, length or maximum authorised weight.
