Answer: A fully managed, serverless NoSQL database for high-performance applications.
The correct answer is A, Amazon DynamoDB. It is a fully managed, serverless, key-value NoSQL database that is designed to deliver single-digit millisecond performance at any scale. DynamoDB is known for its ability to provide consistent, low-latency access to large amounts of data, making it ideal for applications that require high performance and scalability. The other options, while they are all AWS database services, do not match the specific criteria of being a key-value database with sub-millisecond latency. Amazon Aurora is a relational database, Amazon DocumentDB is a document database compatible with MongoDB, and Amazon Neptune is a graph database.
