You are developing a model to identify the factors that lead to sales conversions for your customers. You have completed processing your data. You want to continue through the model development lifecycle. What should you do next?

Answer options

• A. Use your model to run predictions on fresh customer input data.
• B. Monitor your model performance, and make any adjustments needed.
• C. Delineate what data will be used for testing and what will be used for training the model.
• D. Test and evaluate your model on your curated data to determine how well the model performs.

Correct answer: C

Explanation

The correct answer is C because defining the data for testing and training is crucial before any evaluation or predictions can take place. Without this step, the model cannot be properly trained or assessed. Options A, B, and D are steps that occur after the training and testing data has been defined.
