In SAS Model Manager, the champion/challenger framework is configured for a credit scoring model. The challenger receives 20% of scoring requests. After 30 days, the challenger's Gini (0.71) exceeds the champion's Gini (0.66) with statistical significance. What action does the champion/challenger framework enable?

B is correct because the champion/challenger framework in SAS Model Manager is a governance tool that enables controlled A/B-style evaluation of a new model (challenger) against the production model (champion). Performance comparison data supports the decision to promote the challenger, but promotion requires human review and approval through the SAS Model Manager workflow — it is not automatic. A is wrong; promotion is not automatic. C is wrong; the challenger can be promoted, not automatically discarded. D is wrong; the framework is designed to lead to a promotion decision, not perpetual parallel operation.
