What lateral distance must we leave when overtaking a pedestrian on a conventional road?

A)1.5 metres minimum.Correct
B)That proportional to the width and characteristics of the carriageway.
C)1 metre maximum.
When overtaking pedestrians, animals, two-wheeled or animal-drawn vehicles, vehicles immobilized on the road, or assistance vehicles when they are carrying out aid and rescue operations outside built-up areas, the manoeuvre must be carried out occupying part or all of the adjacent lane of the carriageway.
If there is more than one lane in our direction, the adjacent lane must be fully invaded, and a lane change is mandatory when overtaking cycles, mopeds or groups of them.
In any case, the lateral separation shall not be less than 1.50 metres. When overtaking a vehicle other than the above, or when the overtaking takes place in a built-up area and is not of a cycle or moped, a lateral safety margin proportional to the speed and to the width and characteristics of the carriageway shall be left, When overtaking a cycle or moped in a built-up area, we must leave a lateral separation of not less than 1.50 metres, just as we do outside built-up areas. For those who have doubts about overtaking pedestrians in built-up areas:
As we have already mentioned, when overtaking a pedestrian in a built-up area we will leave a lateral safety margin proportional to the speed and to the width and characteristics of the carriageway.
