Which approach is considered best practice to assess the top predictors in order to get to a meaningful and robustmodel?

A dataset for building the Einstein Discovery story contains 72 fields that are potentially relevant predictors.

Which approach is considered best practice to assess the top predictors in order to get to a meaningful and robustmodel?
A . This dataset is too big and cannot be used in Einstein Discovery. Request a new dataset with fewer predictors.
B. Build the story with all the predictors and indicate that Einstein Discovery should show the top predictors.
C. Go back to the datapreparation and reduce the number of fields to less than 30 in order to produce a story.
D. Build a story with a first set of predictors and assess which predictors are important to the story. Then drop the less important ones and add the predictors thatwere omitted in the first run and assess their impact.
