Which action will accomplish this?

Explanations:

Enabling Amazon S3 versioning allows you to keep multiple versions of an object, enabling recovery from accidental deletion.

Amazon S3 Intelligent-Tiering is used for cost management by automatically moving objects between access tiers; it does not provide recovery from deletions.

An Amazon S3 lifecycle policy is used to manage object storage over time but does not prevent data loss due to accidental deletion.

Cross-Region replication duplicates objects to another bucket in a different region, but it does not provide versioning or protection against accidental deletions.
