D
Multiple threads trying to use the ConnectionFactory object simultaneously will throw an exception.
E
In a multithreaded scenario, connection objects cannot be safely created from the ConnectionFactory.
Correct Answer:
B
A connection factory supports concurrent use, enabling multiple threads to access the object simultaneously.
A session and its message producers and consumers can only be accessed by one thread at a time (i.e. the access must be synchronized). Their behavior is undefined if multiple threads access them simultaneously.
