Correct Answer: B

Oracle SQL database can be installed on Amazon EC2 instance for full control of the database. It provides users full access to the operating system level of the resources. Amazon EC2 instances can also be used in case Oracle database versions or features are not supported by Amazon RDS.

• Option A is incorrect as Amazon DynamoDB is suitable for NoSQL database & not for Oracle SQL database.
• Option C is incorrect as running a database using Amazon RDS will not provide full access to the database. With Amazon RDS, users do not get access to operating systems of the DB instance. Amazon RDS is a managed solution for highly scalable ,highly available, secure databases in AWS cloud. With the database running on an Amazon EC2 instance , the customer is responsible for managing the instance , which includes routine patching & maintenance work. Customers also have to manage backups, scalability & redundancy of  databases.  With Amazon RDS , the underlined DB instance is managed by AWS.
• Option D is incorrect as  Amazon Aurora is a relational database which is compatible with MySQL & PostgreSQL. It is not compatible with Oracle SQL databases.
