Answer: A

Explanation:

Scenario: App1 has the following data requirements:

✑ Each instance will write data to a data store in the same availability zone as the instance.

✑ Data written by any App1 instance must be visible to all App1 instances.

Azure Cosmos DB: Each partition across all the regions is replicated. Each region contains all the data partitions of an Azure Cosmos container and can serve reads as well as serve writes when multi-region writes is enabled.
