As a WebService the EJB is being accessed via HTTP so A and D are irrelevant i.e. no ORB requests involved. As ODR is built in to the plugin in 8.5.5 Answer B should be correct.

The configuration of the ODR in the DMZ is not supported

As per IBM link https://www.ibm.com/developerworks/websphere/techjournal/0310_alcott/alcott.html
EJB clients communicate with application servers over several ports:
BOOTSTRAP_ADDRESS: Bootstrap port for finding name service, fixed.
ORB_LISTENER_ADDRESS: TCP/IP port, dynamic by default.
so, given above scenario, I go with Answer A.
