Answer: Migrate to Amazon RDS for Oracle, setting up a standby database in a different Availability Zone.
The correct answer is D: Migrate to Amazon RDS for Oracle, setting up a standby database in a different Availability Zone. This solution minimizes operational overhead because AWS manages the RDS environment, including backups, patching, and maintenance. Additionally, creating a standby database in another Availability Zone within the same AWS Region provides high availability and disaster recovery capabilities. The company can still have access to the database's underlying operating system by using Amazon RDS features such as enhanced monitoring and custom database options.
