The recipe to use for auto-updating a parent when all subitems are done:

• A. When any subitem changes status, update the parent item
• B. When all subitems of an item have the status of something, change the item's status to something
• C. When all subitems are done, auto-hide the parent item
• D. When all subitems have different statuses, update the parent item accordingly

Answer: (B)

Auto-updating a parent when all subitems are finished relies on a condition that waits for every subitem to reach a completed state before changing the parent. This ensures the parent only moves to done when nothing remains in progress, reflecting true overall completion. The statement captures this by saying: when all subitems of an item have the status of something, change the item's status to something. In practice, you’d choose the specific final status (like Done) for both the subitems and the parent. The other options trigger updates under incomplete or ambiguous conditions (any change, auto-hiding, or all subitems having different statuses), which can misrepresent the actual completion state.
