Why are you required to stop now?

You answered correctly by selecting both the cyclist and the green vehicle. In situations where you are required to stop, German traffic rules say you must always give priority to vulnerable road users like cyclists, especially if they are in or about to enter your path. Additionally, you must also stop if another vehicle, such as the green vehicle, has right of way or creates a situation that legally requires you to stop for safety. Recognizing both reasons helps you react properly to complex traffic situations and avoid accidents, as both the presence of a cyclist and the movement of the green vehicle can each be a valid reason to stop. This is important for making safe and legal decisions while driving in Germany.
