Explanation
Cloud CDN backed by Cloud Storage is the optimal architecture for serving images with low latency and minimal storage cost. Cloud Storage provides cheap, durable object storage specifically designed for binary assets like images. Cloud CDN caches that content at Google's globally distributed edge locations, so users receive images from a nearby point of presence rather than the origin bucket - dramatically reducing latency. App Engine (A) is an application runtime, not designed for static asset delivery. Compute Engine with Persistent Disk (B) is more expensive and requires managing VMs. Transfer Appliance with Cloud Filestore (C) is for migrating large datasets, not serving web content.
