A: Amazon Macie can scan S3 buckets for sensitive data and identify PII.

E: EventBridge can trigger the Lambda function automatically when Macie detects sensitive data, creating an automated workflow.

AWS Documentation Extract:

"Amazon Macie automatically discovers, classifies, and protects sensitive data in AWS. You can use EventBridge to invoke a Lambda function for post-processing, such as applying Object Lock legal hold to flagged objects."

B, D: Moving to Glacier Deep Archive or applying retention in governance mode is not specific to deletion prevention pending review.
