Selected Answer: C
By modifying the existing RDS instance through the console and enabling the Multi-AZ option, the database will be automatically replicated to a standby replica in a different Availability Zone. In the event of a primary instance failure or maintenance activity, Amazon RDS will automatically failover to the standby replica, minimizing downtime and ensuring high availability.

C is correct however in case you wonder why D is no is due to no "--ha" flag. If "--multi-az" was specifed, that would have been valid too
