Select the appropriate code that inserts elements into the list based on the given key value.(head and trail are dummy nodes to mark the end and beginning of the list, they do not contain any priority or element)

public void insert_key(int key,Object item) 
{
	if(key<0)
	{
		Systerm.our.println("invalid");
		System.exit(0);
	}
	else
	{

		if(count == 0)
		{
			head.setNext(temp);
			temp.setNext(trail);
		}
		else
		{
