Explanation

Explanation

Option B is correct because AWS CloudFormation cannot delete an S3 bucket that contains objects - this is a fundamental AWS constraint. Since the custom resource copied content into the bucket, the bucket is non-empty when CloudFormation attempts deletion. The fix is to modify the custom resource's Lambda function to handle the Delete event by emptying the bucket before CloudFormation attempts to remove it, ensuring clean deletions for this and all future stack versions.

Why the distractors are wrong:

• Option A is incorrect because a static website configuration alone does not prevent bucket deletion - the bucket being non-empty is the actual blocker.
• Option C is incorrect because a missing deletion policy on the custom resource is not the root cause; the issue is the bucket's contents, not the resource's lifecycle policy.
• Option D is partially related but points to modifying the S3 bucket resource itself (e.g., using a DeletionPolicy) rather than the custom resource, which is the correct place to handle cleanup since it was responsible for putting the content there in the first place.

Memory Tip: Think of it this way - "whoever makes the mess cleans it up." The custom resource populated the bucket, so its Delete handler should empty it. CloudFormation never deletes a non-empty S3 bucket, no exceptions.
