B Correct answer
Explanation

Database duplication using RMAN was introduced in Oracle9i Database, allowing direct duplication from backups (option B is correct). This feature was not available in Oracle8i (option A is incorrect). Oracle10g and Oracle11g came later with enhanced features, but the core functionality existed since 9i. This is an important feature for creating test databases or disaster recovery.
