27. What is correct about event handling in Java?
A) Java 1.0 event handling is compatible with event delegation model in Java 1.1
B) Java 1.0 and Java 1.1 event handling models are not compatible
C) Event listeners are the objects that implements listener interfaces.
D) You can add multiple listeners to any event source, then there is no guarantee that the listeners will be notified in the order in which they were added.
Answer:BCD
For C, I didn't see anything meaningful for this answer. First, there is not 'listener' interface. If you say it is a general speaking, it is a bad sentence here.

It is fine. "Listener interfaces" is the proper way to refer to the family of interfaces used for event handling. Every Java book will refer to them that way.
