50. You host your company’s static website in the App Engine Flex service. You are leveraging Google’s Cloud CDN (Content Delivery Network) to cache content close to your users. Your company wants to optimise the CDN costs and has asked you to identify a way to improve the cache hit ratio. What should you do?

A. Update cache keys to remove the protocol (HTTP/HTTPS).
B. Move static content to a Cloud Storage Bucket, set up a load balancer for the bucket and direct requests from Google CDN to the load balancer.
C. Set cache expiration time to a lower value.
D. Set caching location header HTTP: Cache-Region to a GCP region closest to users.
