Options:
A. To encrypt data at rest
B. To manage access permissions for buckets and objects
C. To automate data backups
D. To monitor bucket usage
Answer: B
Explanation: S3 bucket policies are JSON-based documents that define access permissions, allowing you to grant or deny access to buckets and objects based on conditions like IP addresses or AWS accounts.
