Final answer:
The best method for Abby to share a snapshot of her calendar with another user is by taking a screenshot. This is a simple, quick, and secure way to share the exact view of her current calendar.
Step-by-step explanation:
If Abby wishes to share a snapshot of her calendar with another user, the most straightforward option for her would be to take a screenshot of the calendar and send it to the other user. This method is quick and captures the calendar exactly as it is seen on her screen, without giving the other user any access to alter or view any additional details.
Choosing to Email Calendar may share more information than necessary, and Configure a delegate would grant ongoing access rather than providing a simple snapshot. Publish online would make the calendar publicly available, which likely is not intended for private sharing. Therefore, taking a screenshot is the optimal choice for this purpose.
