C is correct because SAS Model Manager maintains complete model version history. When a new champion is promoted, the prior champion is archived (not deleted), preserving code, metadata, and performance history for audit trails, regulatory compliance, and rollback. A is wrong; models are not deleted. B is wrong; automatic retraining of archived models does not occur. D describes a deliberate champion/challenger setup, not default archiving.
