Which of the following is the correct way to access all elements of the Queue collection created using the C#.NET code snippet given below?

Queue q = new Queue(); 
q.Enqueue("Sachin"); 
q.Enqueue('A'); 
q.Enqueue(false); 
q.Enqueue(38); 
q.Enqueue(5.4);

IEnumerator e;
e = q.GetEnumerator(); 
while (e.MoveNext())
Console.WriteLine(e.Current);

IEnumerable e;
e = q.GetEnumerator(); 
while (e.MoveNext()) 
Console.WriteLine(e.Current);

IEnumerator e;
e = q.GetEnumerable(); 
while (e.MoveNext()) 
Console.WriteLine(e.Current);

IEnumerator e;
e = Queue.GetEnumerator(); 
while (e.MoveNext()) 
Console.WriteLine(e.Current);
