Example Code Ch 13-3
Assume that countIt and sumIt methods receive a parameter, Node temp, which references the first Node in a linked list where Node is a class that consists of data instances int info and Node next, and further assume that the int variables count and sum are initialized to 0.
-Refer to Example Code Ch 13-3: Which of the following methods could be used to count the number of items in the linked list?

• A) public int countIt(Node temp)
• {
• While (temp != null)
• {
• Count += temp.info;
• Temp = temp.next;
• }
• Return count;
• }
• B) public int countIt(Node temp)
• {
• While (temp != null)
• {
• Count++;
• }
• Return count;
• }
• C) public int countIt(Node temp)
• {
• While (count != null)
• {
• Count++;
• Temp = temp.next;
• }
• Return count;
• }
• D) public int countIt(Node temp)
• {
• While (temp != head)
• {
• Count++;
• Temp = temp.next;
• }
• Return count;
• }
• E) public int countIt(Node temp)
• {
• While (temp != null)
