An AI audit report identifies a finding that an organization lacks a documented AI model inventory. Under which audit reporting criterion should this finding be classified?

B is correct because absence of an AI model inventory is a significant governance control gap — it prevents effective model risk oversight, prioritization, and compliance monitoring, warranting classification as a significant deficiency with a required remediation timeline. A understates the severity of a foundational governance gap. C is inappropriate because this is a governance deficiency, not a fraud indicator. D is a disproportionate response.
