you must not overtake or pass other vehicles (with the exception of light vehicles) at or within 30 meters of the pedestrian crossing or bicycle crossing

Answer: A — True

Safety around pedestrian and bicycle crossings means you should not overtake another vehicle within 30 meters of a crosswalk. This helps prevent surprises for pedestrians or cyclists who may start crossing and gives drivers ahead enough time to react without sudden lane changes. There is an exception for light vehicles, which may overtake in this zone when it’s safe, but other vehicles must not pass. So the statement is true because it matches that rule and its exception.
