A. B. C. D.Answer - C.
Amazon ElastiCache is a web service that makes it easy to deploy, operate, and scale an in-memory data store or cache in the cloud.
The service improves the performance of web applications by allowing you to retrieve information from fast, managed, in-memory data stores, instead of relying entirely on slower disk-based databases.

Amazon ElastiCache is a fully managed, in-memory caching service that makes it easy to deploy, operate, and scale an in-memory cache in the cloud. ElastiCache supports two open-source in-memory caching engines, Redis and Memcached.
In this scenario, since the company wants to store their most frequently used data to improve the response time for the application, using a caching service is a good solution. Caching involves storing frequently accessed data in a temporary storage area so that it can be quickly retrieved without the need to access the original data source, which can improve the application's performance.
Option A and B suggest using MySQL as the data store, but these solutions do not provide a caching mechanism, and as a result, they may not be able to meet the company's requirement for improved response time.
Option D suggests using Amazon DynamoDB, which is a NoSQL database that can store and retrieve any amount of data and can serve as a primary data store for a web application. However, it does not provide caching capabilities by itself. Although, DynamoDB Accelerator (DAX) is a caching layer for DynamoDB that can provide fast access to frequently accessed data.
Therefore, the best option for the company's requirement is Amazon ElastiCache, which can improve the response time of the application by caching frequently accessed data in memory, reducing the time it takes to retrieve the data from the original data source.
