It should be the D as AWS docs explicitly notes:
“Amazon RDS Multi-AZ deployments provide enhanced availability and durability for database instances, making them a natural fit for production database workloads. When you provision a Multi-AZ database instance, Amazon RDS synchronously replicates your data to a standby instance in a different Availability Zone (AZ).”

Correct: B
It must be B, Concurrency is all about performance when high volume of users try to connect to the database
