• Chose B1

  Usually, None values are converted to 0 in data cleaning and preparation process. The key point here is, we don't require any other tool than DataPrep to identify and modify the value

• Chose D1

  Cloud Dataflow is ideal for scalable data processing and allows for real-time transformations. Logistic regression requires numerical (real-valued) inputs, and null values cannot remain as they are.

• Chose D2

  Option D: Using null value conversion to 0 is the most correct practice for this case. Accompanying it with a script allows us to implement the necessary logic to handle null cases properly, adapting to the model while maintaining data integrity.
