Given that a static method doIt() in a class Work represents work to be done, what block of code will succeed in starting a new thread that will do the work? CODE BLOCK a: Runnable r = new Runnable() { public void run() { Work.doIt(); } }; Thread t = new Thread(r); t.start(); CODE BLOCK b: Thread t = new Thread() { public void start() { Work.doIt(); } }; t.start(); CODE BLOCK c: Runnable r = new Runnable() { public void run() { Work.doIt(); } }; r.start(); CODE BLOCK d: Thread t = new Thread(new Work()); t.start(); CODE BLOCK e: Runnable t = new Runnable() { public void run() { Work.doIt(); } }; t.run(); ["Code block a.","Code block B.","Code block c.","Code block d.","Code block e."]
