Since the first node is the head, we can simply move the head pointer to the second node using the line of code "head = head.getNext();". This will remove the first node from the list and make the second node the new head. Options A and B do not consider the case where the first node is being deleted and will cause errors in the code. Option D will delete the entire list, not just the first node.
