Below is a memory diagram of a LinkedIntList object. Which of the code fragments below the diagram would insert the number 50 between the 11 and 12?

Node newNode = new Node();
newNode.item = 50;
newNode.next = first;
first = newNode;

		Node newNode = new Node(); newNode.item = 50; newNode.next = first.next.next; first.next = newNode;
		Node newNode = new Node(); newNode.item = 50; newNode.next = first.next; first.next = newNode;
		Node newNode = new Node(); newNode.item = 50; newNode.next = null; first.next.next = newNode;
