C,D Correct answer
Explanation

In NOARCHIVELOG mode, database recovery to a specific point in time or incomplete recovery is impossible because redo logs are not archived. Thus, if a data file is lost, the database must be restored from a cold backup (losing all changes since), or the affected tablespace must be dropped, losing all its data.
