Final answer:
Choose 'absolute to displayed date' for a flip tab in an appointment book to link directly to a specified time based on the date shown, ensuring constancy over a variable reference point.
Step-by-step explanation:
If you want to create a flip tab in an appointment book that advances to a specified time based on the date being viewed, the best option would be to choose d. absolute to displayed date. This option would directly link the flip tab to the specific date shown, regardless of the current or any other relative date. Choosing 'absolute' ensures that the tab is specific and constant for that date, irrespective of when 'today' is. In contrast, the 'relative to' options would change based on a moving reference point, like today or the current date being viewed, which can vary each day or view.
To create a flip tab that advances your appointment book to a specified time based on the date being viewed, you would choose option c. relative to displayed date. This means that the tab will update the time relative to the date currently being shown on the appointment book. For example, if the appointment book is currently displaying the date March 15th, selecting the flip tab will advance the time to the next available time slot on March 15th.
