Wait, an ETL tool? That feels too manual for real-time updates!

I don't recall much about ETL tools, but I think they are more for batch processing rather than real-time updates, so option D seems off to me.

I feel like option C with the Apex Trigger might not be the best choice since it’s synchronous, and we need asynchronous integration, right?

I'm not entirely sure, but I remember something about using Platform Events for event-driven architecture. Could that be option A?

I think the "source" element corresponds to the location of the 'apple' IPS repo, so I'll go with option E.

I'm leaning towards B - Closed - No Action. The question doesn't specify that the defect is being fixed, just that it's being considered as part of a new project.
