I believe option B sounds correct since it mentions being triggered by the conflicts feed, which seems relevant to resolving conflicts directly.

I think we practiced a similar question where we had to choose between triggers. If I recall, the conflicts feed is the right one to use here.

I remember something about using the conflicts feed, but I'm not sure if it should be a pull or push method.

Based on the information provided, I believe the correct answer is option B. Receiving items pushed from the conflicts feed and using an Azure Cosmos DB trigger seems like the most direct way to resolve the conflicts.

Okay, let's see here. I think the key is to use the conflicts feed to resolve the conflicts, since the runtime exception is preventing the custom merge procedure from working.

Ah, the old 'runtime exception preventing conflict resolution' trick. Classic Azure Cosmos DB. Definitely going with B, the Cosmos DB trigger function.

Wait, why would I want to pull items from the change feed? That's not gonna help me resolve the conflicts caused by the runtime exception. Gotta go with B, the Cosmos DB trigger.
