What are the two advantages of RMAN Block Media Recovery （BMR） over file/x7flevel recovery？（）

• A、BMR lowers the mean time to recover （MTTR）.
• B、BMR supports point­in­time 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 that requires a recovery can remain online.
