Answer: Amazon Inspector

The correct answer is D, Amazon Inspector. Amazon Inspector is an automated vulnerability management service that continually scans Amazon EC2 instances, AWS Lambda functions, and container workloads for software vulnerabilities and unintended network exposure. It uses a set of predefined rules to assess the security state of your resources, analyzing network activity, operating system configurations, and application behavior to identify potential security issues. The assessment report provides detailed findings and recommendations for remediation, which aligns with the company's requirement for an automated security assessment report identifying unintended network access and operating system vulnerabilities on EC2 instances.
