I think Not C becuse the application is deployed in two AZ. Multi-AZ RDS works in primary-stanby instance fashion. There will not be efficient for the application as it is deployed in 2 AZ.

Because Multi-AZ provides reliability w.r.t Availability Zone (AZ) where as question mentions reliability w.r.t Regions (AWS regions)

I think Multi-AZ can't across regions, which means you have to deploy RDS in two az in a single region.

B Amazon Aurora Global Database is designed for globally distributed applications, allowing a single Amazon Aurora database to span multiple AWS regions. It replicates your data with no impact on database performance, enables fast local reads with low latency in each region, and provides disaster recovery from region-wide outages
