• C. Where the after-images are applied to the database
• D. Continuing without any recovery
• E. Switching to an existing copy of the database

The correct option is A Where the before-images are applied to the database.

Backward recovery applies the journal file to the active database, moving backwards from the end of the file. Backward recovery uses 'before-image' journaling.
