Which AWS service meets these requirements?

Explanations:

AWS Snowball is a data transfer service that helps move large amounts of data to and from AWS. It is not primarily designed for long-term storage or durability.

Amazon S3 (Simple Storage Service) is designed for durability, scalability, and cost-effectiveness. It can store large amounts of data, including call recordings, for long periods like 6 years.

AWS Storage Gateway is primarily a hybrid cloud storage service that enables on-premises applications to use AWS storage. It is not suitable for long-term data retention by itself.

Amazon Kinesis is a service for real-time data processing and analytics. It is not designed for long-term data storage, making it unsuitable for retaining call recordings.
