A company has a latency-sensitive trading platform that uses Amazon DynamoDB as a storage backend. The company configured the DynamoDB table to use on-demand capacity mode. A solutions architect needs to design a solution to improve the performance of the trading platform. The new solution must ensure high availability for the trading platform.
Which solution will meet these requirements with the LEAST latency?

A. Create a two-node DynamoDB Accelerator (DAX) cluster. configure an application to read and write data by using DAX.

B. Create a three-node DynamoDB Accelerator (DAX) cluster. configure an application to read data by using DAX and to write data directly to the DynamoDB table.

C. Create a three-node DynamoDB Accelerator (DAX) cluster. configure an application to read data directly from the DynamoDB table and to write data by using DAX.

D. Create a single-node DynamoDB Accelerator (DAX) cluster. configure an application to read data by using DAX and to write data directly to the DynamoDB table.
