A. Amazon DynamoDB "Amazon DynamoDB is designed to run high-performance, internet-scale applications that would overburden traditional relational databases. With over ten years of pioneering innovation investment, Amazon DynamoDB offers limitless scalability with consistent single-digit millisecond performance and up to 99.999% availability." https://aws.amazon.com/dynamodb/features/#Performance_at_scale

Amazon DynamoDB would be the best option in this scenario as it is a fully managed NoSQL database service that is designed to provide single-digit millisecond latency and consistent performance at scale. DynamoDB is also highly available, fault-tolerant, and can automatically scale up or down based on demand, making it a great choice for applications with variable workloads.
