The correct answer is C. AWS Schema Conversion Tool.

AWS Database Migration Service (AWS DMS) is a fully-managed service that makes it easy to migrate relational databases, data warehouses, NoSQL databases, and other types of data stores. AWS DMS helps you migrate your data to and from most widely used commercial and open-source databases such as Oracle, MySQL, PostgreSQL, Microsoft SQL Server, MariaDB, Amazon Aurora, and more.

AWS Schema Conversion Tool (AWS SCT) is a standalone application that helps you migrate your database schema from one database engine to another. It supports homogeneous migrations (migrations between the same type of database engines) and heterogeneous migrations (migrations between different types of database engines).

When performing a heterogeneous migration with AWS DMS, you use AWS SCT to convert your database schema and code to a format that's compatible with the target database engine. AWS SCT analyzes your source schema and code, and provides recommendations for converting it to the target database engine. You can use AWS SCT to convert your schema and code for many popular database engines, including Oracle, Microsoft SQL Server, PostgreSQL, and MySQL.

AWS Application Discovery Service is used to help you plan your migration to AWS by identifying your on-premises applications, their dependencies, and their performance characteristics. AWS Server Migration Service is used to automate the migration of your on-premises virtual machines to AWS. AWS Migration Hub provides a central place to track and manage your application migrations to AWS.
