Answer: Using Read Replica feature

The correct answer is B - Using Read Replica feature. **Explanation:** - **Read Replica feature** allows you to create read-only copies of your database instance in the same AWS Region or in different AWS Regions. Cross-region read replicas enable you to replicate data to another region for disaster recovery or to serve read traffic from locations closer to your users. - **Multi-AZ feature** (Option A) provides high availability within a single AWS Region by maintaining a synchronous standby replica in a different Availability Zone, but it does not replicate data to another region. - **Database Migration Service** (Option C) is used for migrating databases to AWS, not for ongoing replication. - **AWS Backup** (Option D) is for backup and recovery purposes, not for real-time data replication. For more information on cross-region read replicas, refer to the AWS blog post: https://aws.amazon.com/blogs/aws/cross-region-read-replicas-for-amazon-rds-for-mysql/
