Why each option

For an application requiring a data store that can scale to receive millions of database queries each second, Amazon DynamoDB is the appropriate AWS service.

AAmazon DynamoDBCorrect

Amazon DynamoDB is a fully managed, serverless NoSQL database that delivers single-digit millisecond performance at any scale, making it ideal for high-throughput, low-latency applications that process millions of requests per second.

BAWS Cloud9

AWS Cloud9 is a cloud-based integrated development environment (IDE) and not a database service.
