C Correct answer
Explanation

Round-robin partitioning distributes rows sequentially across partitions (row 1→partition 1, row 2→partition 2, etc.). Interleave reverses this by reading rows sequentially from each partition (partition 1 row 1, partition 2 row 1, etc.), effectively restoring the original order and undoing the round-robin effect.
