C)Yes, when the lanes are marked and the road is within a built-up area.Correct
As a general rule, overtaking must always be carried out on the left. Exceptionally, within built-up areas where drivers may use whichever lane best suits their destination, overtaking may be carried out on the right, but only when the lanes are marked. If the lanes are not marked, you must drive on the right and overtake on the left. There are other cases where overtaking on the right is permitted: - When a vehicle is clearly indicating its intention to change direction to the left or to stop on that side and there is sufficient space to overtake it on the right safely.
