What is the right course of action?

Your answer is correct because pedestrians always have priority at pedestrian crossings, even if they are not regulated by traffic lights or signs. In this situation, both pedestrians on the crosswalk have the right of way, and you must wait for them to cross before proceeding.

The other options are incorrect because you must never force pedestrians to wait or hurry when they are on a pedestrian crossing. Also, you cannot just pass before one pedestrian while expecting the other to wait; both have priority, so you must let them cross completely.

Remember, in German traffic rules, vehicles must yield to pedestrians at marked crossings to ensure their safety. This is one of the fundamental rules designed to protect vulnerable road users.
