The Google Cloud Storage offering that also serves as a Content Delivery Network (CDN) is option D, Cloud Storage.

Google Cloud Storage is an object storage service that allows users to store and retrieve data in a highly scalable, secure, and durable manner. It offers various storage classes to meet different performance and cost requirements, including Standard, Nearline, Coldline, and Archive.

In addition to its primary storage capabilities, Cloud Storage also provides a built-in content delivery network (CDN) known as Cloud CDN. Cloud CDN uses Google's globally distributed edge points of presence (PoPs) to cache content closer to end-users, reducing latency and improving the overall performance of web applications and services.

When Cloud CDN is enabled for a Cloud Storage bucket, the content is automatically cached at the edge locations, and subsequent requests for the same content are served from the nearest edge location rather than going back to the origin server. Cloud CDN can be configured to use a variety of caching strategies, including time-based, region-based, and URL-based, to optimize content delivery and ensure the best possible user experience.

In summary, Cloud Storage is a versatile object storage service that can also function as a content delivery network through its built-in Cloud CDN capability, making it an excellent choice for web applications and services that require fast, reliable, and cost-effective content delivery.
