A company is building data processing pipelines by using AWS Glue.

Option B is correct because access to specific S3 folders for AWS Glue jobs should be restricted by scoping permissions to the correct S3 object ARNs in the IAM policy Resource element, such as bucket paths with wildcard patterns for the allowed prefixes. Time-based access is then enforced by adding a Condition that uses the global IAM condition key aws:CurrentTime with date operators such as DateGreaterThan and DateLessThan. AWS IAM documentation explicitly states that date condition operators are used with aws:CurrentTime or aws:EpochTime in the Condition element.

Option C is not the best answer because s3:prefix is generally used with bucket listing operations rather than as the main mechanism to control object-level access for Glue reads and writes. For object access, the cleanest least-privilege design is to scope the allowed object ARNs directly. Option A is incorrect because $util.time is not an IAM policy condition key. Option D uses the wrong S3 condition key for the stated requirement. The uploaded study guide also emphasizes granting AWS Glue access through an IAM service role with the right scoped permissions, which fits this pattern.
