NewsMIDlet and CalendarMIDlet are in different MIDlet suites. Neither has any static push registrations.

Suppose NewsMIDlet registers dynamically for datagram push notifications on port 79.

What happens if a method CalendarMIDlet.init() attempts to open a UDPDatagramConnection on port 79?

A. init() succeeds without user confirmation, and removes NewsMIDlet's registration for datagram push connections.

B. init() fails to open the connection.

C. init() succeeds only with user confirmation.

D. init() succeeds without user confirmation, and leaves untouched NewsMIDlet's registration for datagram push connections.
