假设有一个链表的节点定义如下：

struct Node { int data; Node* next;};

现在有一个指向链表头部的指针：Node* head。如果想要在链表中插入一个新节点，其成员data的值为42，并使新节点成为链表的第一个节点，下面哪个操作是正确的？（）

Node* newNode = new Node; newNode->data = https://tiku.scratchor.com/paper/question_answer/42; newNode->next = head; head = newNode;

Node* newNode = new Node; head->data = https://tiku.scratchor.com/paper/question_answer/42; newNode->next = head; head = newNode;

Node* newNode = new Node; newNode->data = https://tiku.scratchor.com/paper/question_answer/42; head->next = newNode;

Node* newNode = new Node; newNode->data = https://tiku.scratchor.com/paper/question_answer/42; newNode->next = head;
