Answer: Amazon RDS

The correct answer is C, Amazon RDS. Amazon Relational Database Service (Amazon RDS) is a managed database service that simplifies database administration tasks such as provisioning, patching, backup, recovery, and scaling. It supports Oracle databases, allowing the company to offload many time-consuming database administration activities and focus more on their application development and business needs. Amazon ElastiCache (A) is used for in-memory caching, Amazon EC2 (B) provides scalable compute capacity, and Amazon DynamoDB (D) is a NoSQL database service, neither of which are the best fit for the company's requirement to minimize database administration for an Oracle database.
