The correct answer is C, Amazon RDS. Amazon RDS (Relational Database Service) is a managed database service provided by AWS that supports various database engines including MySQL. It simplifies the process of setting up, operating, and scaling a relational database in the cloud. Amazon RDS handles time-consuming administrative tasks such as hardware provisioning, database setup, patching, and backups, allowing you to focus on application development and data management. The other options are incorrect for the following reasons: A) Amazon DynamoDB is a NoSQL database service, not a relational database service. B) Amazon Redshift is a fully managed, petabyte-scale data warehouse service, not a service for managing MySQL databases. D) AWS Database Migration Service (AWS DMS) is a service for migrating databases to AWS, not for provisioning managed MySQL instances.
