Suggested Answer: F 🗳️
The goal of a page restore is to restore one or more damaged pages without restoring the whole database. Typically, pages that are candidates for restore have been marked as "suspect" because of an error that is encountered when accessing the page.
Note: Requirements for Restoring Pages
A page restore is subject to the following requirements:
✑ The databases must be using the full or bulk-logged recovery model.
Etc.

While a point in time restore could be done, it is overkill. A page restore will try to restore just the pages that are damaged, and not the whole database as in a restore.
