Selected Answer: C
Multi-Az is only for disaster recovery and does not allow active-active configuration where users can read from all times as the question suggests. In order to satisfy this then read replicas need to be utilized. https://www.whizlabs.com/blog/aws-rds-multi-az-read-replica/

C . With Amazon RDS, you can create a MariaDB, MySQL, Oracle, or PostgreSQL read replica in a different AWS Region from the source DB instance. Creating a cross-Region read replica isn't supported for SQL Server on Amazon RDS.

B is the answer. Multi-AZ is for high availability. Question says it has to be online at all times. if the primary RDS in one AZ goes down, then only read replicas will be there and you can't write data anywhere until a read replica instance is made the Primary / Master.

Read replicas is not create stanby node. Multi-AZ support read replicas and create stanby node. I choose B.

Scenario clearly states "The company needs a solution in which its data is available and online across multiple AWS Regions at all times". ---- Data must be available acrss multiple REGIONS ---> Create read replicas in another region. C!
