I think STS authorization is the best choice. It provides temporary credentials.

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’m a bit confused about the difference between Bucket Policy and Object Policy. I feel like either could work, but I can't recall the specifics.

I remember practicing a question about STS authorization before, so I’m leaning towards B) STS authorization for temporary access.
