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
