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.

Definitely, the Cosmos DB trigger is the best option for resolving conflicts in this scenario.

Yeah, pulling items from the change feed won't solve the issue. B is the way to go.

I think B is the right choice too. The Cosmos DB trigger will help us resolve the conflicts.

I think the answer is B, because it mentions receiving items pushed from the conflicts feed.
