Which of the following loop correctly prints the elements of the array? char[ ] arr = new char[ ] {'k', 'i','C', 'i','t'} ;

• do { Console.WriteLine((char) i); } while (int i = 0; i < arr; i++);
• foreach (int i in arr) { Console.WriteLine((char) i); }
• for (int i = 0; i < arr; i++) { Console.WriteLine((char) i); }
• while (int i = 0; i < arr; i++) { Console.WriteLine((char) i); }
• do { Console.WriteLine((char) i); } until (int i = 0; i < arr; i++);
