B Correct answer
Explanation

The FBEAN package is Oracle Forms' built-in interface for communicating with JavaBeans. It provides PL/SQL built-ins to register JavaBeans, set/get properties, and invoke methods. Using FBEAN eliminates the need to write custom Java wrapper code or implement custom integration layers - it's the standard, supported mechanism for Forms-JavaBean interaction.
