Final answer:
German law mandates drivers to leave a distance of at least 1.5 meters when passing cyclists in cities and 2 meters outside of cities. The provided options do not specify the context, but the closest answer is 2 meters.
Step-by-step explanation:
German law stipulates that when passing cyclists, drivers must leave a minimum distance of 1.5 meters in cities and 2 meters outside of cities. Since this question does not specify whether it is inside or outside a city, the most comprehensive answer would be to give both distances. However, given the options provided, the closest correct option to the actual legally required distance within a city would be 2 meters. It is important to adhere to this regulation for the safety of cyclists and to avoid legal penalties.
