You observe that the schema for the generated web service input is based on the dataset and includes the label column that the model predicts. Client applications that use the service must not be required to submit this value. You need to modify the inference pipeline to meet the requirement. What should you do?

A. Add a Select Columns in Dataset module to the inference pipeline after the dataset and use it to select all columns other than the label. 
B. Delete the dataset from the training pipeline and recreate the real-time inference pipeline.
 C. Delete the Web Service Input module from the inference pipeline. 
D. Replace the dataset in the inference pipeline with an Enter Data Manually module that includes data for the feature columns but not the label column.
