Amazon RDS (Amazon Relational Database Service) is a managed service that allows you to easily set up, operate, and scale a relational database in the cloud. This service is specifically designed for running relational databases such as MySQL, PostgreSQL, Oracle, and SQL Server. Unlike Amazon DynamoDB, which is a NoSQL database service, or Amazon Redshift, which is a data warehousing solution, Amazon RDS is focused on providing a fully managed relational database service. While Amazon S3 is a storage service, it does not provide relational database capabilities. So, the correct answer is A as it is the only option that matches the description of the service that provides a managed relational database.
