Selected Answer: B
the best solution for meeting the requirements with the lowest latency of reads and writes would be to implement Amazon DynamoDB global tables in each of the six Regions. DynamoDB global tables automatically replicate data across multiple Regions, allowing for low-latency reads and writes. Additionally, global tables support multi-master writes, which means that each Region can handle read and write requests for all of the users, improving the scalability of the solution.
