B Correct answer
Explanation

Preserving partitioning minimizes data copying between parallel stage operators because when stages maintain the same partitioning scheme, data doesn't need to be repartitioned or moved between processing nodes. Combinability mode and Execution Mode control stage behavior but don't directly address data copying, while Don't combine mode isn't a standard DataStage term for minimizing data movement.
