For a non-empty linked list, select the code that should appear in a function that adds a node to the end of the list. newPtr is a pointer to the new node to be added, and lastPtr is a pointer to the current last node. Each node contains a pointer nextPtr, a link to a node.

Question 25 options:

	A) lastPtr->nextPtr = newPtr;lastPtr = newPtr;
	B) (b) lastPtr = newPtr;lastPtr->nextPtr = newPtr;
	C) (c) newPtr->nextPtr = lastPtr;lastPtr = newPtr;
	D) (d) lastPtr = newPtr;newPtr->nextPtr = lastPtr;
