B Correct answer
Explanation

Rollup aggregates multiple input records into fewer output records based on a key. For example, if you have 100 sales records and rollup by product, you might get 10 output records (one per product). Sort maintains the same record count. Reformat and Redefine Format also preserve record count - they transform structure, not quantity.
