I'm not sure about the other options, but D definitely sounds like the most comprehensive approach. Handling failures across multiple services can be tricky, so having a centralized way to manage that is key.

Option D seems like the way to go. Using a Choreographer and Event Bus to handle failed scenarios seems like a robust and flexible solution for maintaining data consistency in a microservices architecture.
