Using the textbook's implementation of a linked list, why is the LinkedListIterator inner class NOT declared as an inner static class?
A)Because the LinkedList class must have access to the instance variables of the LinkedListIterator class.
B)Because the Node class must have access to the instance variables of the LinkedListIterator class.
C)Because the LinkedListIterator class must have access to Node class instance variables.
D)Because the LinkedListIterator class must have access to LinkedList class instance variables.

The LinkedListIterator class needs to access the instance variables of the LinkedList class, such as the head of the list, to iterate through the list. Making it a non-static inner class allows it direct access to the LinkedList's instance variables. Static inner classes, on the other hand, do not have access to the instance variables of the outer class.
