LOG_ARCHIVE_DEST_2 = 'SERVICE = stdb1'
DB_RECOVERY_FILE_DEST = '/u01/oradata'
Examine the following RMAN command issued to set the deletion policy for archived log files:

TO BACKED UP 2 TIMES TO sbt;
Which statement is true regarding what this command accomplishes?
A. All archived redo log files backed up at least twice to tape are deleted.
B. All archived redo log files backed up at least once to tape are eligible for deletion.
C. All archived redo log files backed up at least twice to tape are deleted from the flash recovery area.
