Which action can be taken to reorder the rules list in QuickBooks?

To reorder the rules list in QuickBooks, utilizing the grip on the edge to drag is the most effective method. This action allows users to quickly and intuitively reposition the rules in a desired sequence. Since the dragging mechanism is designed specifically for reordering, it makes the process straightforward and user-friendly.

Other options like deleting rules or recreating the list don't provide a functional way to reorder existing rules, and sorting by date would not achieve the desired rearrangement based on user preference. Therefore, dragging with the grip is the optimal approach to customize the order of rules within QuickBooks.
