Explanation

Option A: While this helps identify runtime issues and integration problems, it does not address the specific task of reviewing an image for vulnerabilities. This step should come after ensuring the image is free from known vulnerabilities. Option B: This is the correct answer because vulnerability scanning tools are specifically designed to identify known vulnerabilities in container images. These tools analyze both the image layers and dependencies, providing a comprehensive list of vulnerabilities that need to be addressed. This is a critical first step before proceeding with deeper analysis or deployment. Option C: Resource utilization metrics are used for performance monitoring and optimization, not vulnerability identification. They do not provide any insights into the security posture of the container image. Option D: This is an important step, but it is not the most critical first step. Manual inspection is prone to human error and cannot detect vulnerabilities in the underlying dependencies or base
