I think B) STS authorization is the best choice. It provides temporary access.

I have a feeling that C) Bucket Policy is the right choice since it can control access at the bucket level, but I need to double-check my notes.

I think the answer might be A) RAM Policy, but I'm not entirely sure how it specifically handles user isolation.
