For the questions below, assume Node is a class consisting of an int info and a Node next and header is a HeaderNode that has Node front, rear and int count where front references the first item in the list, rear references the last item in the list and count is the number of elements in the list.

Previously, to iterate through a linked list, we used a while loop. Which of the following for-loops could replace the previous while loop that would start at head and go until temp == null?
◦ for (Node temp = header.front, int j = 0; j < header.count; temp = temp.next) { ... }
◦ for (int j = 0; j < header.count; j++) { ... }
◦ for (Node temp = header.front; temp != header.rear; temp = temp.next) { ... }
◦ for (Node temp = header.front, int j = 0; j < header.count; temp = temp.next, j++) { ...}
◦ for (Node temp = header.front, int j = 0; j < header.count && temp != header.rear; temp = temp.next, j++) { ... }
