Which of the following is a risk practitioner's BEST course of action if a risk assessment identifies a risk that is extremely unlikely but would have a severe impact should it occur?

Rating the risk as high priority based solely on impact might misrepresent its overall risk score if likelihood is extremely low, and it doesn't specify a course of action beyond prioritization.

Obtaining management's consent to accept the risk without first analyzing treatment options might be premature and irresponsible, as there might be cost-effective ways to reduce the impact or likelihood.

Ignoring a risk with severe impact, regardless of likelihood, is irresponsible and a failure of risk management duty, as the organization would be completely unprepared if it materialized.

When a risk has a severe impact, even with an extremely low likelihood, it represents a significant potential threat to the organization. The best course of action is to analyze various treatment options (mitigate, transfer, avoid, accept) to develop a strategic response, ensuring the organization has a plan to manage potential consequences should the unlikely event occur, demonstrating due diligence and preparedness.
