B) the recursive method should be one of the methods specified in the List interface
C) the recursive method should be made private,and should be called by a public non-recursive method
D) the recursive method should not call itself outside of its base case

The recursive method should be made private to avoid access by external classes and should be called by a public non-recursive method to initiate the recursion. It is not necessary to subclass the linked list class or override a method of the same name. It is also not a requirement for the recursive method to be one of the methods specified in the List interface. Finally, the recursive method can call itself outside of the base case, as this is necessary for the recursion to continue until the base case is reached.
