Answer: A

Explanation:

With Azure Cosmos DB, you can add or remove the regions associated with your account at any time.

Multi-region accounts configured with multiple-write regions will be highly available for both writes and reads. Regional failovers are instantaneous and don’t require any changes from the application.
