Answer: Increasing days of payables only

## Explanation - **Option A: Increasing days of payables only** - This positively affects operating cash flows because it means the company is taking longer to pay its suppliers, which preserves cash in the business for a longer period. - **Option B: Increasing days sales outstanding only** - This NEGATIVELY affects operating cash flows because it means the company is taking longer to collect from customers, which ties up cash in receivables. - **Option C: Both increasing days of payables and increasing days sales outstanding** - While increasing days payables helps, increasing days sales outstanding hurts operating cash flows, so the net effect is uncertain and likely less beneficial than just increasing days payables. Therefore, only increasing days of payables consistently and positively affects operating cash flows.
