A risk assessment team is evaluating an AI system that uses facial recognition to grant physical access to secure facilities. Beyond accuracy, which risk category deserves the MOST emphasis in the risk assessment for this use case?

B is correct because facial recognition systems are well-documented to have significantly higher error rates for darker-skinned individuals and women — making differential error rates across demographic groups the primary additional risk requiring assessment beyond accuracy. A and D are implementation concerns. C is a technical architecture observation, not a risk specific to this use case.
