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.

D.run a backup validation to populate V$DATABASE_BLOCK_CORRUPTION view， and then repair any corrupt blocks recorded in the view
E.run a backup validation， repair any corrupt blocks found during the validation process， and then update V$DATABASE_BLOCK_CORRUPTION view to indicate which corrupt blocks have been repaired
