   A manufacturing company has a predictive-maintenance model that forecasts equipment failure. The model's performance has been stable for months, but the operations team has noticed that the model's predictions are becoming less useful because the factory has introduced new machinery with different sensor characteristics. The team wants to detect this issue early. What is the most appropriate approach?

   • ARetrain the model monthly with all available data, since the new machinery will be incorporated automatically.
   • BMonitor feature drift on the new machinery's sensor data and set an alert that triggers when drift exceeds a predefined threshold.
   • CMonitor only the model's accuracy on the new machinery's data, since this is the most direct measure of performance.
   • DDisable the model for the new machinery until enough data is collected to retrain it.
