Amazon S3 Standard provides virtually unlimited scalability, high durability (11 nines), and millisecond latency. It is designed for storing large volumes of unstructured content such as media files. S3 also supports pre-signed URLs and direct browser uploads, enabling users to upload files securely without passing through backend servers. EBS volumes (A) are block storage, limited to single AZ, and not suitable for web-scale storage. EFS (B) is a shared file system for POSIX workloads, not for direct browser uploads. S3 Express One Zone (D) offers higher performance for small objects but does not provide cross-AZ durability, making it unsuitable for growing global content. Therefore, option C is the most scalable, durable, and cost-effective solution.
