(8 marks) B) Given the code below: using System; public class Example3 { private static void OnTimedEvent(Object source, System.Timers. ElapsedEventArgs e) { CISO16-2/CIS116-2/PATO01-2/2020-21/SEM1/PAPER 1 Page 3 of 5 Console.WriteLine("The Elapsed event was raised at {0}", e.SignalTime); } public static void Main() { System.Timers. Timer aTimer; aTimer = new System.Timers. Timer(); aTimer. Interval = 100; aTimer. Elapsed += OnTimedEvent; aTimer.Enabled = true; Console.WriteLine("Press the Enter key to exit the program at any time... "); Console.ReadLine(); } wwwwwwwww } Explain why the On TimedEvent method and the Main method must be declared as static. There is one delegate variable in the code, which is it? Delegates are like C++ function pointers but are type safe, explain the role of the delegate in this code
