The process of working with a thread
1. create an object as here
x run= new x();
2. create a thread and attach an object as here
thread t = new thread(run);
3. start the thread
t.start();
1. create an object as here
x run= new x();
2. create a thread and attach an object as here
thread t = new thread(run);
3. start the thread
t.start();

@All
The given answer is correct. Don't get confused.
A. Thread t = new Thread(X);
Wrong. Because, here X is the ClassName not an object.
B. Thread t = new Thread(X); t.start();
Wrong. Because, here X is the ClassName not an object. So thread cannot be started. It would have been correct if it was written like:
Thread t = new Thread(new X()); t.start();
D. Thread t = new Thread(); x.run();
Wrong. Here, object 'x' doesn't make any sense.
But, Option C: is correct
X run = new X(); //Creates objects that implements run() as per Runnable interface
Thread t = new Thread(run); // Creates thread
t.start(); // Starts the thread.
Note: The above three statements can be written as simply
(new Thread(new X()).start();
Hope this help you. Have a nice day!
