A risk manager is evaluating an AI system that assigns individual risk scores to millions of customers daily. The system uses an ensemble of 47 models. Which risk does this level of complexity introduce that a simpler model would not?
Select an answer to reveal the explanation.
Short Explanation and Infographic
Here's the deal — b is correct because ensemble complexity creates interpretability and auditability challenges — understanding why a specific customer received a specific score requires tracing through 47 models' contributions, making explanation, challenge, and audit far more difficult than with a simpler model. A is an infrastructure cost consideration.

Full Explanation
B is correct because ensemble complexity creates interpretability and auditability challenges — understanding why a specific customer received a specific score requires tracing through 47 models' contributions, making explanation, challenge, and audit far more difficult than with a simpler model. A is an infrastructure cost consideration. C is incorrect — ensembles typically outperform single models. D is not an accurate statement of regulatory prohibition.
