The correct answer is B, AWS Artifact. AWS Artifact is a service that provides customers with on-demand access to AWS' compliance documentation, including PCI compliance documentation. This service allows companies to download AWS security and compliance documents, such as AWS ISO certifications, Payment Card Industry (PCI), and System and Organization Control (SOC) reports. These reports can be used to demonstrate compliance with industry standards to auditors. The other options, Amazon Cloud Directory, AWS Trusted Advisor, and Amazon Inspector, do not provide access to compliance documentation.
