A vulnerability has a score of 9.

This refers to the CVSS (Common Vulnerability Scoring System), which CEH v13 identifies as the industry standard for vulnerability prioritization. A score of 9.8 indicates critical severity, combining metrics such as exploitability, impact, privileges required, and scope.

CVSS helps organizations prioritize remediation objectively, focusing resources on vulnerabilities with the highest business risk. It also allows consistent communication between technical and management teams.

Options B, C, and D misrepresent CVSS functionality. Therefore, Option A is correct.
