I'm not sure, but I think option A) After=docker-repository.mount could also work. It specifies that the Docker service should start after the specified mount unit is active.

I agree with Laura. Adding Requires=docker-repository.mount to the Docker service definition will make sure that the service waits for the volume to be mounted before starting.

I think the answer is C) Requires=docker-repository.mount because it ensures that the Docker service will only start if the specified volume is mounted.
