C)Yes, in any case.Correct
Pedestrians have right of way at properly marked pedestrian crossings.
If they are not regulated by traffic lights or a traffic officer, pedestrians always have priority to cross. If, on the other hand, there is a traffic light or a traffic officer at the crossing, they would be the ones granting priority. It does not matter whether it is inside or outside a built-up area.

These crossings are painted to define the place where pedestrians can cross safely.
