What action must you take to remove an item from an order while in the Order Detail screen?

To remove an item from an order while in the Order Detail screen, clicking the DELETE button is the correct action. This function is specifically designed to remove unwanted items from an existing order, ensuring that the order reflects only the items that are truly needed. The DELETE button is typically configured in software interfaces to streamline the process of managing orders, providing a direct and clear way to eliminate errors or incorrect selections.

In contrast, the other actions do not serve the purpose of item removal directly. Pressing the CANCEL button usually signifies that the entire order process should be halted, potentially leading to the loss of all information entered, not just the removal of an individual item. Selecting a REMOVE option may not be available or might refer to a different operation that doesn't explicitly indicate deletion of the item from the order list. Exiting the order process entirely does not address the need for item management and would leave the order unchanged.
