B Correct answer
Explanation

Preserve partitioning minimizes data copying between Parallel Stage Operators by maintaining existing partition schemes. When partitioning is preserved, data stays in its current partition rather than being repartitioned. Combinability mode and Execution Mode affect operator combination, not data movement.
