Which set of actions should the solutions architect take to increase the cache hit ratio as quickly possible?

• B) Update the CloudFront distribution to disable caching based on query string parameters.
• C) Deploy a reverse proxy after the load balancer to post process the emitted URLs in the application to force the URL strings to be lowercase.
