Option A is Correct. The run() method to a thread is like the main() method to an application. 

Starting the thread causes the object's run method to be called in that separately executing 

thread.

Option B is wrong. The start() method causes this thread to begin execution; the Java Virtual 

Machine calls the run method of this thread.

Option C is wrong. The stop() method is deprecated. It forces the thread to stop executing.

Option D is wrong. Is the main entry point for an application.
