Which statement is true about the output result of the following program?
The answer is (b).





When you call t.run(), you start a new thread of execution, hence, you would have two threads in all (the new one %26amp; the main thread). A thread's behavior in most cases is unpredictable as would be here. If pong() is invoked first, Pong would be printed first, else Ping would be printed. Again, anything can happen at runtime!
