Full Explanation
B is correct because in the champion/challenger pattern, the champion handles the bulk of live production traffic while one or more challenger models are exposed to a controlled fraction of traffic. Performance metrics from both are compared to decide whether to promote a challenger. A is wrong because automatic retraining is a separate capability. C describes what happens when a challenger wins — the champion is replaced — but this is the outcome, not the definition of champion status. D is wrong because champion status is based on production deployment, not training accuracy.
