Your database has a backup that was taken yesterday (Tuesday) between 13:00 and 15:00 hours.
This is the only backup you have. You have lost all the archived redo logs generated since the previous
Monday, but you have archived redo logs available from the previous Sunday and earlier. You now need
to restore your backup due to database loss. To which point can you restore your database?
A. 13:00 on Tuesday.
B. 15:00 on Tuesday.
C. Up until the last available archived redo log on Sunday.
D. To any point; all the redo should still be available in the online redo logs.
E. The database is not recoverable

   The database is not recoverable.You would need all the archived redo logs
generated during the backup on Tuesday,at least,to restore the database after
that backup.The online redo logs are very unlikely to have all the redo that would
be required.
