Which statement correctly describes the advantages of using Oracle Autonomous Database?

The advantages of using Oracle Autonomous Database include reduced operational complexity, which is a significant benefit inherent to its design. This cloud-based database service automates many traditional database management tasks, including patching, backups, and tuning, which traditionally required extensive manual intervention. By leveraging machine learning and AI, the Autonomous Database can self-manage and optimize itself, allowing organizations to focus more on application development and strategic initiatives instead of routine database maintenance.

The other options do not align with the primary advantages of the Autonomous Database. Full control over hardware configurations is not typically a feature of a fully managed service like Oracle Autonomous Database, where the underlying infrastructure is abstracted from the user. The requirement for constant manual oversight contradicts the service's core purpose of self-driving capabilities, and limited scalability options would undermine the flexible and scalable nature that organizations seek from cloud-based solutions.
