Selected Answer: A
Enable synchronous replication: Synchronous replication ensures that data is written to both the primary and standby DB clusters before the transaction is committed. This means that the secondary cluster is always in sync with the primary, with minimal lag time, and can be promoted to primary in case of a failure. This approach meets the RPO and RTO requirements and ensures there is no data loss or downtime.

So if we want to have it in the same region, synchronous replication would be a better solution?

No. You can use multi-AZ read replica for single region DR.
