The correct answer is B, 'Using AWS Artifact'. AWS Artifact is a service that provides on-demand access to AWS compliance reports and other relevant documentation. It offers a collection of documents, including AWS compliance reports, certifications, and agreements, which can be helpful for evaluating whether the company's use of the AWS Cloud is compliant with local regulatory standards. AWS Artifact makes it easier to understand and demonstrate how AWS has implemented security and compliance controls in the cloud environment. The other options, such as Amazon GuardDuty, AWS Support, and AWS CloudTrail, do not provide the same level of compliance documentation and are therefore not the correct answer to this question.
