A company is migrating an online marketplace application from a mainframe system to an Auto Scaling group of Amazon EC2 instances. The EC2 instances access an Amazon Aurora cluster. The application requires a scalable, persistent caching solution to store the results of in-progress transactions and SQL queries.

Which solution will meet these requirements?

A
Use an Amazon ElastiCache (Redis OSS) cluster to serve transaction and query results.
B
Use an Amazon CloudFront distribution with an Amazon S3 bucket as the origin to cache the transactions. Add an Amazon EC2 instance store volume to the EC2 instances for query result caching.
C
Use an Amazon ElastiCache (Memcached) cluster to serve transaction and query results.
D
Use an Amazon ElastiCache (Redis OSS) cluster to cache the transactions. Add an Amazon EC2 instance store volume to the EC2 instances for query result caching.
