Amazon S3 Lifecycle configuration rules provide the ability to automatically manage objects throughout their lifecycle. A lifecycle rule can be configured with an Expiration action to direct Amazon S3 to delete objects after a specified number of days since their creation. In this scenario, setting an expiration action for 3 days (72 hours) will ensure that objects are automatically and permanently removed from the bucket, fulfilling the security requirement to prevent them from residing in the bucket for longer than the specified period. This is the most direct and intended method for this use case.

A. S3 Versioning is for preserving, retrieving, and restoring every version of every object stored in a bucket. While lifecycle rules can expire noncurrent versions, versioning itself does not expire the current object.

C. S3 Intelligent-Tiering is a storage class designed to optimize storage costs by automatically moving data to the most cost-effective access tier. It does not inherently handle object expiration.

D. Presigned URLs grant temporary access to an S3 object for a specified duration. The expiration of the URL only revokes access via that URL; it does not delete the object from the S3 bucket.

1. AWS S3 Documentation, "Managing your storage lifecycle": "You can use S3 Lifecycle to define rules that control the lifecycle of your objects... For example, you can create a lifecycle rule that expires all objects with a specific prefix 3 days after creation." This directly supports the use of a lifecycle rule for expiration.

2. AWS S3 Documentation, "Lifecycle action for your object": This document details the Expiration action. It states, "This action expires objects, and Amazon S3 deletes the expired objects on your behalf... You can specify expiration in the following ways: Number of days after object creation."

3. AWS S3 Documentation, "Sharing objects using presigned URLs": "A presigned URL gives you access to the object identified in the URL... The presigned URLs are valid for the specified duration." This confirms that the URL expires, not the object itself.

4. AWS S3 Documentation, "Using versioning in S3 buckets": "Use S3 Versioning to keep multiple versions of an object in the same bucket. For example, you can use versioning to preserve, retrieve, and restore every version of every object stored in your buckets." This clarifies that versioning's primary purpose is object preservation, not timed deletion.
