Selected Answer: B
B not C because C. Migrate the database to an Amazon Aurora multi-master DB cluster. While this provides high availability and is designed for write-intensive workloads, it's generally more complex and may be more costly. It's suitable for specific use cases where you need write scaling across multiple masters, which might not be necessary here.

Selected Answer: C
C. Migrate the database to an Amazon Aurora multi-master DB cluster: Amazon Aurora multi-master enables multiple instances to write to the database simultaneously. This can provide high availability and fault tolerance, making it suitable for write-intensive workloads. It supports read and write operations across multiple instances, which is beneficial for multi-tenant workloads where different tenants may have different write patterns.
