You are working on the PROD database， which is in NOARCHIVELOG mode. You lost the active online redo log group due to a media failure. How should you recover your database？（）A、 Restore the database from a whole consistent backup and start the database in MOUNT mode. Then， open the database with the RESETLOGS option after performing a cancel-based recovery.B、 Restore the database from a whole consistent backup and start the database in MOUNT mode. Then， drop the lost redo log group and open the database with the RESETLOGS option after performing a cancel-based recovery.C、 Restore the database from a whole consistent backup and start the database in MOUNT mode. Then， clear the lost redo log group and open the database with the RESETLOGS option after performing a cancel-based recovery.D、 Do nothing. You do not need to recover the database in this case； an instance recovery will be performed by the SMON process on startup.
