    Every Sunday， consistent backups are performed on your database. Because of a user error， you performed an incomplete recovery on Tuesday and opened the database with the RESETLOGS option. A user error occurs again on Thursday， which necessitates an incomplete recovery. Sunday’s backup is the most recent backup available. What would you do in this scenario？（）
    A

    recovery cannot be performed because a backup was not performed after the last incomplete recovery

    B

    restore all the files from Sunday’s backup， and then perform an incomplete recovery up to the point in time when the user error occurred on Thursday

    C

    restore all the files from Sunday’s backup， and then recover up to the point in time when the RESETLOGS operation was performed on Tuesday

    D

    restore all the files from Sunday’s backup， and open the database to reset the database to the point in time when the backup was performed on Sunday
