Correct answer: Amazon RDS.
Why this is the answer
Amazon RDS (Relational Database Service) is the correct choice because it is a managed service that automates tasks like hardware provisioning, database setup, patching, and backups for relational databases. This significantly reduces operational overhead compared to self-managing databases. Amazon EC2 instances would require the company to manually install, configure, and maintain the database software and underlying operating system, increasing operational effort. Amazon DynamoDB is a NoSQL database service, not suitable for SQL databases. OpenSearch is a search and analytics engine, not a relational database service.
