What are the two advantages of RMAN Block Media Recovery （BMR） over file-level recovery？（）

• A、 BMR lowers the mean time to recover （MTTR）.
• B、 BMR supports point-in-time recovery of individual data blocks.
• C、 BMR enables you to use incremental backups for block recovery.
• D、 BMR enables recovery even when the database is not mounted or open.
• E、 BMR enables you to use proxy backups to perform block media recovery.
• F、 BMR enables increased availability of data during recovery because the data file requires a recovery can remain online.
