Selected Answer: B

Option B is the correct choice: #B. Create an origin access identity and grant it permissions to read objects in the S3 bucket. When using Amazon CloudFront as a content delivery network with an S3 bucket as the origin, it's a best practice to restrict direct access to the S3 bucket and require users to access objects only through CloudFront URLs. This can be achieved by creating an Origin Access Identity (OAI) and granting it permission to read objects in the S3 bucket.
