The primary objective of this project is to accurately predict customer churn (C), as this directly addresses the business's need to retain customers. Evaluating the model's performance (A) is a secondary objective, crucial for ensuring the model's predictions are reliable and meet both business and regulatory standards. Option E suggests that both objectives are equally primary, but while both are essential, prediction accuracy is the ultimate goal, with evaluation serving to validate this goal. Options B and D, while important for data handling and preparation, do not represent the primary or secondary objectives of the project.
