The correct answer is AWS Artifact, as it offers on-demand access to security and compliance reports and other governance-related documents provided by the cloud provider. These are essential for companies in the healthcare industry to ensure they're meeting regulatory standards like HIPAA. Amazon RDS is a database service and does not provide compliance documentation. AWS Trusted Advisor offers optimization recommendations but does not supply compliance reports. AWS Identity and Access Management (IAM) is focused on securing access to services and resources and does not provide documentation on compliance with healthcare laws.
