The correct answer is A. Subjective and based on an individual's experience. Using likelihood and consequence ratings is a qualitative risk analysis technique, and its primary limitation is that ratings are inherently subjective and depend on the analyst's personal experience and judgment.

Why each option

Using likelihood and consequence ratings is a qualitative risk analysis technique, and its primary limitation is that ratings are inherently subjective and depend on the analyst's personal experience and judgment.

ASubjective and based on an individual's experience.Correct

Qualitative risk analysis assigns descriptive labels such as high, medium, or low based on individual or team judgment rather than measured data, meaning two analysts with different backgrounds or risk appetites can produce conflicting results for the same asset. This subjectivity makes it difficult to achieve consistent, repeatable, or auditable risk assessments across an organization.

BRequires a high degree of upfront work to gather environment details.

Requiring a high degree of upfront work to gather environment details is a characteristic limitation of quantitative risk analysis, which demands detailed data collection such as asset values and historical loss rates - not of the lightweight qualitative approach.

CDifficult to differentiate between high, medium, and low risks.

Qualitative methods using likelihood-consequence matrices are specifically designed to differentiate between risk levels, so difficulty distinguishing between high, medium, and low risks is not a recognized limitation of this approach.

DAllows for cost and benefit analysis.

The ability to perform cost-benefit analysis is actually a strength of quantitative risk analysis, not a limitation of the qualitative likelihood-consequence approach, and therefore is not a drawback.

ECalculations can be extremely complex to manage.

Extremely complex calculations are a limitation associated with quantitative risk analysis involving statistical modeling or Monte Carlo simulations, not with the comparatively simple qualitative matrix approach.
