Couldn't have said it better than JoeTromundo

C: Incomplete multipart uploads consume unnecessary storage and increase costs, especially with large files like videos. Setting a lifecycle policy to automatically delete incomplete uploads after 7 days helps reduce unnecessary storage costs without manual intervention. E: The videos are frequently accessed in the first 180 days and rarely accessed after that. Transitioning the videos to S3 Standard-IA after 180 days reduces costs while still providing immediate retrieval when needed. S3 Standard-IA is designed for infrequently accessed data and offers lower storage costs than S3 Standard while maintaining fast access times. Why not B? S3 Transfer Acceleration improves upload speeds for users with poor internet connectivity, but it INCURS ADDITIONAL COSTS. While this can help with uploads, it does NOT directly optimize STORAGE COSTS, which is the main goal here.

CE for sure. Why not B? The root cause for failed upload is due to that fact that user has poor internet connectivity. That's not something transfer accelerator can help with, maybe the user need to find a better internet provider, or use Elon's star link

CE are the best options. In option C, incomplete upload should be deleted to save costs.

From the cost management perspective, the answer should be CE

Cost Optimization so CE

Cost Optimization so CE

B - for transfers of files over long distances between your client and an S3 bucket | E - for reducing cost for data that is accessed less frequently.

C - optimizes the S3 storage costs effectively E - address frequent access in the first 180 days and infrequent access afterward

B and E are the only ones that make sense to me
