In Access press TAB

In Microsoft Access, when you press the TAB key, it is used to exit the currently active combo box or list box. This is especially helpful when you are navigating through forms or data entry fields. It allows you to move to the next field or control after making a selection in a combo box or list box without needing to use the mouse. TAB is not used to move up or down lines or pages. Therefore, the correct option is Option C: Exit the combo box or list box.
