D) error checking.

Answer 1

The data entry screen displaying the customer name and address when a correct customer number is entered is an example of closed-loop verification.

Step-by-step explanation:

The correct answer is C) closed-loop verification.

Closed-loop verification is a process in which data entered into a computer system is immediately checked for accuracy and completeness, and the system provides feedback to the user based on the verification process. In this case, when the student enters a correct customer number, the data entry screen displays the customer name and address as feedback.

For example, let's say the student enters the customer number 12345. The system verifies the entered number against the database and retrieves the associated customer name and address, which are then displayed on the screen. This immediate feedback confirms that the entered number was correct and provides the relevant customer information to the user.
