  2. Modulus

  3. Entire

  4. Same

D Correct answer
Explanation

Same partitioning has the lowest CPU cost because it performs no actual repartitioning - it simply maintains the existing partition scheme from the previous parallel stage. No data movement and no key calculation means zero overhead. Range and Modulus require key computations, while Entire broadcasts all data to every partition (high network cost).
