B.When the linked list represented by an object/instance of class LL is empty, the head and tail references point to null. C.An object/instance of class LL can represent a linked list that allows nodes to be added at the tail end only. D.The advantage of having the reference to the tail node along with the head node in class LL is that we can start searching the list from the tail node and continue till the head node, until we have found the element or the search has failed.
