Your company requires all its developers to use a well-specified set of exception classes to model several common error conditions, many of the which are specific to its business. These exception classes are centrally maintained and come packaged in a library (a JAR file). The application you are developing needs to report a number of error conditions covered by this library to remote clients.

Which paring of component type and remote access technology enables client applications to use the predefined exceptions as part of their natural programming model?

A. Servlet accessed using HTTP

B. Entity bean accessed using web services

C. Stateless session bean accessed using Remote Method Invocation (RMI)

D. Message-driven bean accessed using Java Message Service (JMS) queue
