Which keyboard shortcut reveals the entry field for the personal recovery key in macOS when FileVault is enabled?

This shortcut is specifically designed to facilitate access to the recovery options during the login process when FileVault is active.

When FileVault is enabled on a Mac, it encrypts the startup disk to protect user data.

By pressing this particular keyboard combination, users can bring up the field needed to input their personal recovery key, allowing them to regain access to their system.

The other options do not correspond to the designated shortcut for accessing the recovery key entry field. The keyboard shortcuts for macOS often have specific functions associated with them, and it's important to remember that different combinations may invoke different actions across the operating system's interfaces.
