c. CORBA & JDBC
d. None of the above
Answer:
a. RMI & COBRA
Explanation:
CORBA interfaces are defined in IDL and RMI interfaces are defined in Java. RMI-IIOP allows you to write all interfaces in Java (see RMI-IIOP). CORBA supports in and out parameters, while RMI does not since local objects are passed by copy and remote objects are passed by reference.
