You are using Recovery Manager (RMAN) for backup and recovery operations with a recovery catalog. You have been taken database backups every evening. On November 15, 2007, at 11:30 AM, you were informed that the USER_DATA tablespace was accidentally dropped.On investigation, you found that the tablespace existed until 11:00 AM, and important transactions were done after that. So you decided to perform incomplete recovery until 11:00 AM. All the archive logs needed to perform recovery are intact. In NOMOUNT state you restored the control file that has information about the USER_DATA tablespace from the latest backup. Then you mounted the database. Identify the next set of commands that are required to accomplish the task? ()A. AB. BC. CD. D
