Answer: AWS Database Migration Service

The correct answer is C, AWS Database Migration Service (AWS DMS). AWS DMS is a managed service designed to facilitate the migration of databases to AWS with minimal downtime and without data loss. It supports a wide range of source and target databases, including the migration of a MySQL database to Amazon RDS. AWS Direct Connect (A) is used to establish a dedicated network connection between the AWS network and a user's on-premises environment, but it does not perform database migrations. AWS Server Migration Service (B) helps migrate servers to AWS but is not specifically designed for database migrations. The AWS Schema Conversion Tool (D) helps in converting a database schema from one database engine to another, but it does not perform the actual data migration.
