Which AWS service provides highly durable object storage?

Explanations:

Amazon S3 (Simple Storage Service) is designed for highly durable object storage, providing 99.999999999% (11 nines) durability. It is ideal for storing and retrieving any amount of data from anywhere on the web.

Amazon Elastic File System (EFS) provides scalable file storage for use with AWS Cloud services and on-premises resources, but it is not specifically designed for object storage like S3.

Amazon Elastic Block Store (EBS) provides block storage for use with Amazon EC2 instances. While it offers durability, it is not an object storage service and is meant for storage volumes rather than objects.

Amazon FSx provides fully managed file systems, including Windows File Server and Lustre file systems, but it does not offer the same level of durability or the object storage capabilities that Amazon S3 provides.
