A machine learning engineer is trying to perform batch model inference. They want to get predictions using the linear regression model saved at the path model_uri for the DataFrame batch_df. batch_df has the following schema: customer_id STRINGThe machine learning engineer runs the following code block to perform inference on batch_df using the linear regression model at model_uri: In which situation will the machine learning engineer’s code block perform the desired inference?

1. A. When the Feature Store feature set was logged with the model at model_uri — đáp án hiện tại
2. B. When all of the features used by the model at model_uri are in a Spark DataFrame in the PySpark
3. C. When the model at model_uri only uses customer_id as a feature
4. D. This code block will not perform the desired inference in any situation.
5. E. When all of the features used by the model at model_uri are in a single Feature Store table
